Computation and analysis of the polarization degree for bremsstrahlung at peripheral scattering
An economic technique for calculation of polarized bremsstrahlung process is proposed, assuming typical atomic momentum transfer q << m. The adopted approach is based on the natural reduction of the matrix element to the form Vαγα + A₅γ⁵. Polarization distribution in the fully differential cro...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | An economic technique for calculation of polarized bremsstrahlung process is proposed, assuming typical atomic momentum transfer q << m. The adopted approach is based on the natural reduction of the matrix element to the form Vαγα + A₅γ⁵. Polarization distribution in the fully differential cross-section is analyzed. It is found that at a given momentum transfer to the atom polarization in the plane of small radiation angles is oriented along circles passing through two common points. It is shown that with angular selection of radiated photons carried out, even with momentum transfers to the atom being integrated over, for particular radiation angles polarization may stay as high as 100%. Without angular selection of photons, only by control of the recoil, it is impossible to gain radiation polarization above 50%. |
