碩士 === 國立中央大學 === 物理研究所 === 82 === We calculate the unpolarized bremsstrahlung cross section,
differential with respect to emitted photon energy for the atom
with atomic number Z=13 and 79, and for incident electrons of
low kinetic energy 0.5, 1.0 and 2.0 keV. Here k is the photon
energy. It is an relativistic calculaton by relating the
bremsstrahlung cross section to the elastic scattering cross
section in the first Born approximation for screened
potential. Our results show that the atomic-electron screening
effect on the bremsstrahlung photon energy spectrum increases,
as the incident kinetic energy and the ratio of the photon
energy to the incident kinetic energy decrease, and as Z
increases. The calculation becomes better as the incident
kinetic energy decreases, and as the ratio of the photon energy
to the incident kinetic energy increases.
