Numerical results from a calculation of the positron bremsstrahlung spectrum in a partial-wave expansion are presented for Z = 8, 92 at photon energies 10, 50, and 500 keV. Data are presented both for a point-Coulomb potential and for a screened Hartree-Slater central potential. Comparison is made with the corresponding electron bremsstrahlung. In the point-Coulomb case the nonrelativistic Sommerfeld formula or the Elwert factor provides a quantitative prediction of the ratio of the two spectra for Z = 8, qualitative for Z = 92; similar accuracy is achieved in the screened case with a ratio of screened normalization. The positron spectrum is strongly suppressed for lowenergy positrons, which cannot penetrate toward the repulsive central potential. For high-energy positrons or longdistance interactions the positron spectrum approaches the electron spectrum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
