Universal cross sections for K-shell ionization by low-velocity protons: importance of relativistic and energy-loss effects
Journal Article
·
· Phys. Rev., A; (United States)
Recent data reported by Zander and Andrews for K-shell ionization of /sub 22/Ti, /sub 26/Fe, /sub 28/Ni, and /sub 30/Zn by 60 to 150-keV protons are reanalyzed in terms of the ECPSSR theory of Brandt and Lapicki. The ECPSSR approach takes into account the energy-loss effect (E) as well as the Coulomb deflection (C), perturbed-stationary state (PSS), and relativistic (R) effects. Agreement between theory and experiment is improved, and the remaining discrepancies are partially attributed to inaccuracies of the wave functions utilized in the calculation of inner-shell ionization cross sections.
