To the memory of Alexej Sitenko (Oleksij Sytenko)
Ukrainian and world science has suffered an irrelievable loss. A prominent the-
orist in physics, brilliant individual, true Ukrainian patriot Alexej Sitenko (Oleksij
Sytenko) passed away on February 11, 2002, one day before his 75th birthday.
Alexej Sitenko was born on February 12, 1927, in the Novi Mlyny village of the
Baturyn region in Chernihivshchyna, Ukraine. In 1949 he graduated (with distinc-
tions) from Kharkiv State University and continued his postgraduate studies under
the supervision of academician Akhiezer. In 1952 he became Ph.D., in 1959 – Doctor
of Science in Physics and Mathematics. During the years 1952–1959 he was assistant
professor and in 1960–1961 – full professor in the theoretical physics department of
Kharkiv University.
In 1961 Prof. Sitenko moved to Kyiv and began his work at the Institute of
Physics as the head of the newly created department of theoretical nuclear phy-
sics. In 1964 Prof. Sitenko, together with Prof. M.M.Bogolyubov, founded the sub-
department of nuclear and elementary particles theory at the physical department of
Taras Shevchenko State University and headed it for about ten years. Alexej Sitenko
had been a professor of Taras Shevchenko University since 1963 till the last days of
his life.
Since 1968 Professor Sitenko has worked at the Bogolyubov Institute for Theo-
retical Physics of the National Academy of Sciences of Ukraine, since 1988 he has
been the Director of the Institute.
In 1967 A.Sitenko was elected the Correspondent Member, in 1982 – Member of
the Ukrainian Academy of Sciences. He was Foreign Member of the Royal Swedish
1
Academy of Sciences (since 1991), Honorary Member of the Hungarian Academy
of Sciences (since 1997), Member of the American Physical Society, Correspond
Member of the International Union of Radio Science.
Professor Sitenko was the author of over 400 papers in various fields of theoretical
physics, author and co-author of 17 books and manuals in nuclear and plasma physics
whose English translations were published in the USA and in Great Britain. His
books belong to the classics of physics. They are constantly used by professors and
students of many universities and widely referred to in literature. It should be noted
that his “Nuclear Theory” is the first book in this field published in the Ukrainian
language.
Prof. Sitenko’s scientific interests concerned mainly theoretical nuclear physics
and plasma theory. In particular, he was a pioneer in the development of the kinetic
theory of plasmas with external magnetic fields. He was the first who obtained the
plasma dielectric permittivity tensor in the kinetic approximation and employed the
results to formulate the most general dispersion equations for waves in magnetoactive
plasmas with regard for particle thermal motion. He found the general solution of the
problem of electromagnetic field generation in a plasma with an arbitrary electric
current distribution, calculated energy characteristics of these fields and derived
general relations for the polarization vectors of electromagnetic waves propagating
in the plasma.
Professor Sitenko has made basic contribution in the development of the statisti-
cal theory of electromagnetic processes in plasma-like media. Together with academi-
cian Akhiezer he worked out the kinetic theory of electromagnetic fluctuations in
plasmas. In particular, he calculated fluctuation spectra for various quantities (elec-
tron and ion densities, electric and magnetic field intensities, microscopic particle
distribution functions), found cross-sections of wave scattering and transformation
by plasma fluctuations, revealed peculiar features of the spectra of scattered radi-
ation associated with collective phenomena occurring in plasmas. He predicted the
phenomenon of combination wave scattering in plasmas and developed a theory of
induced wave scattering taking into account the parametric effect of the external
field and nonlinear saturation of induced fields. Prof. Sitenko’s theory of wave scat-
tering in plasmas has provided a basis for an advanced method of noncontact plasma
diagnostics that is widely used in the studies of both native and laboratory plas-
mas. It is not an exaggeration that nearly all scientific papers in this field contain
references either to pioneer papers by A.Sitenko or to the relevant sections of his
books.
An important stage in the development of the fluctuation theory was the ex-
tension of the fluctuation-dissipation relation to nonequilibrium systems and the
inversion of the fluctuation-dissipation theorem, proposed by Prof. Sitenko.
An important part of the research carried out by Prof. Sitenko is devoted to
the study of nonlinear wave interactions and to the effect thereof on plasma fluc-
tuations. He calculated nonlinear dielectric susceptibilities (both scalar and tensor)
and derived nonlinear equations for electromagnetic fields and correlation functions
of fluctuating quantities. These equations are applied to study the nonlinear satu-
2
ration of critical fluctuations in unstable plasmas, anomalous transport in turbulent
plasmas, and to work out the renormalized plasma electrodynamics.
During the past few years, Prof. Sitenko and his students have studied fluc-
tuations in turbulent and dusty plasmas. They formulated microscopic equations
for dusty plasmas which consistently describe self-consistent field and particle dis-
tributions with regard for electron and ion absorption by dust grains, derived the
Bogolyubov-Born-Green-Kirkwood-Yvon chain of equations for such plasmas and
considered stationary distributions and fluctuations of grain charges. These papers
laid the foundation of a consistent kinetic theory of dusty plasmas.
Professor Sitenko obtained significant results in theoretical nuclear physics. His
fundamental contribution in the theory of high-energy particle-nucleus interactions
is of basic importance. His theory of diffraction nuclear processes is called “Sitenko-
Glauber method” in literature and is widely used to draw information on the nuclear
structure. In terms of this theory, he predicted a new physical phenomenon, deuteron
diffraction dissociation, that was later confirmed experimentally. Prof. Sitenko for-
mulated the generalized Huygens principle for diffraction hadron-nuclear interac-
tions. He was the first who substantiated the application of phenomenological opti-
cal nuclear potentials in terms of microscopic scattering amplitudes. He proposed a
comprehensive theory of high-energy nuclear processes in complex nuclear systems
of various nature, worked out a theory of inclusive reactions involving light ions.
The diffraction theory of multiple scattering, developed by Prof. Sitenko and his
school, considerably influenced the studies of the interaction of complex particles
with nuclei. Sitenko-Glauber theory is recognized by the specialists in the scientific
centers throughout the world.
Professor Sitenko worked much on the analysis of high-energy electron-nucleus
interactions. He was the first who considered inelastic scattering of fast electrons by
nuclei accompanied by nucleon knockout and studied the effect of nucleon correla-
tions on the inelastic scattering spectra.
Prof. Sitenko also made an important contribution to the theory of direct nuclear
reactions involving polarized particles and to the theory of three-body systems. He
derived integral equations for three-nucleon systems with regard for spin and isospin
degrees of freedom and proposed new methods of solution thereof.
Prof. Sitenko obtained interesting results concerning relativistic nuclear systems,
worked out the Hamiltonian approach in the formulation of relativistic equations for
systems of strongly interacting particles.
Prof. Sitenko’s scientific interests concerned all the most important fields of nu-
clear and plasma physics. His fundamental results are widely recognized in Ukraine
and abroad. In 1976 he was awarded the K.D.Synelnykov Prize for a series of papers
concerning the theory of nuclear reactions. A series of his fundamental papers on
the theory of electromagnetic fluctuations and nonlinear wave interactions in plas-
mas was distinguished by the National Prize of Ukraine in 1992. In 1994 he was
awarded (together with O.M.Sharkovsky) the M.M.Bogolyubov Prize for the scat-
tering theory in quantum systems and in one-dimensional dynamical systems. In
1996 Prof. Sitenko was awarded the title of Honored Scientist of Ukraine. In 2000
3
he was awarded the International Walter Thirring Prize for the great contribution
in the development of theoretical nuclear physics.
Prof. Sitenko always combined his research work with the education of young
scientists. His books, based on the original lecture courses, were used by generations
of young theorists to study the fundamentals of nuclear theory, theory of nuclear
reactions, physical kinetics, plasma electrodynamics. Of his students, 19 have become
Doctors of Sciences in Physics and Mathematics and 46 have obtained the Ph.D.
degree. Representatives of his scientific school work in the leading scientific centers
in Kyiv, Kharkiv, Dnipropetrovsk, Odesa, Tbilisi, Moscow, Tashkent, Sofia, Prague,
Hanoi, Paris, Nancy.
Professor Sitenko was highly active in the organization of scientific research as
Director of the Bogolyubov Institute for Theoretical Physics, member of the Board
of the Division of Physics and Astronomy of the National Academy of Sciences
of Ukraine, Editor-in-Chief of the Ukrainian Journal of Physics, Director of the
International Center of Physics of the Division of Physics and Astronomy of the
National Academy of Sciences of Ukraine, member of the Physical division of the
State Committee of the National Prizes of Ukraine in science and technology.
Professor Sitenko initiated the international conferences on plasma theory. The
first and the second conferences were held in Kyiv at the Institute for Theoretical
Physics in 1971 and 1974. The conferences were highly successive and since then have
been called “Kiev (Kyiv) Conferences”. Beginning from 1977, the conferences bear-
ing this name have been held in various countries. Prof. Sitenko brought important
contribution into the organization of a series of international conferences “Nonlin-
ear and Turbulent Processes in Physics” (Kyiv 1979, 1983, 1987, 1989, 1992, 1994)
whose success is generally acknowledged. Prof. Sitenko was among the organizers
of the first international conference “Physics in Ukraine” (Kyiv, 1993) and Interna-
tional Bogolyubov Conference “Problems of Theoretical and Mathematical Physics”
(Moscow-Dubna-Kyiv, 1999).
Fond memories of Professor Sitenko will always live in the hearts of those who
knew him.
