Notes

Copyright 1985 American Physical Society. The following article appeared in Physical Review A, 32:4, http://link.aps.org/doi/10.1103/PhysRevA.32.2088

Abstract: L-shell x-ray production cross sections by ₁¹H+ ions are reported. The data are compared to the first Born approximation (plane-wave Born approximation for direct ionization and Oppenheimer-Brinkman-Kramers approximation for electron capture) and to the ECPSSR (energy-loss and Coulomb-deflection effects, perturbed stationary-state approximation with relativistic correction) theory. The energy of the protons ranged from 0.25 to 2.5 MeV in steps of 0.25 MeV. The targets used in these measurements were ₂₈Ni, ₂₉Cu, ₃₂Ge, ₃₃As, ₃₇Rb, ₃₈Sr, ₃₉Y, ₄₀Zr, and ₄₆Pd. The first Born theory generally agrees with the data found in the literature at high energies and overpredicts them below 1.5 MeV. The ECPSSR predictions are in better agreement with experimental cross sections. At 0.25 MeV our data, however, are underestimated by this theory and tend to agree with the first Born approximation.
