Abstract
-shell x-ray production cross sections for the , , , and have been measured for , , and on Yb and Pb and for and on Sm. The energy ranges for the incident-ion species were 0.3 to 2.4 MeV/amu for , 0.15 to 4.4 MeV/amu for , and 0.9 to 3.0 MeV/amu for . Comparisons of the , , and x-ray production cross-section data have been made to the predictions of the plane-wave Born approximation (PWBA) and the PWBA with corrections for Coulomb deflection and/or binding-energy effects. The comparisons show that for the individual x-ray production cross sections, there are problems associated with the binding-energy correction calculations for the and x-ray data. Furthermore, measurements of the ratio of to x-ray intensities do not support the use of an increased effective binding energy in the PWBA formulation.
