L-subshell X-ray production cross sections of Nd, Gd and Er for incident deuterons (0.30–1.00 MeV) and α particles (0.60–2.00 MeV) were measured using standard techniques. It is possible to isolate the Coulomb-deflection and increased-binding effects (which are a part of the perturbed stationary state (PSS) theoretical treatment of these phenomena) by forming ratios of the production cross sections for equal velocity pairs of incident particles (deuterons and protons for the Coulomb-deflection effect, α particles and deuterons for the increased-binding effect). The PSS theory provides a good fit to the experimental results for the Coulomb-deflection effect for all three Subshells for these same three elements [L.A. Rayburn, Nucl. Instr. and Meth. B40/41 (1989) 113]; however, it does not provide a good fit for the increased-binding effect. |
