On the incoherent radiation of relativistic electrons and positrons in crystal
The incoherent bremsstrahlung of high energy electrons in crystal is caused by thermal spread of atoms from their equilibrium positions in the lattice. In the present article the simulation procedure for the intensity of incoherent radiation based on the quasi-classical formulae of the bremsstrahl...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The incoherent bremsstrahlung of high energy electrons in crystal is caused by thermal spread of atoms from
their equilibrium positions in the lattice. In the present article the simulation procedure for the intensity of
incoherent radiation based on the quasi-classical formulae of the bremsstrahlung theory is developed. Substantial
orientation dependence of the intensity of hard incoherent radiation is demonstrated under the angles of incidence of
the particles to the crystallographic plane, close to the critical angle of planar channeling. The dechanneling effect
leads to decrease of that orientation dependence. The results of simulation are in a good agreement with the
experimental data. |
