L-shell x-ray-production cross sections in lead by proton bombardment (240-440 keV).

Abstract

The L-shell x-ray-production process in lead (Pb) by proton impact over the energy range 240\char21{}440 keV has been studied. The x rays emitted from a thin (44.4\ifmmode\pm\else\textpm\fi{}3.9 \ensuremath{\mu}g/${\mathrm{cm}}^{2}$) Pb target were detected using a high-purity Ge low-energy photon spectroscopy detector. The total x-ray cross sections and the x-ray cross sections for the Ll, L${\ensuremath{\alpha}}_{1}$,2, L\ensuremath{\beta}'s, L${\ensuremath{\gamma}}_{1}$, and L${\ensuremath{\gamma}}_{2}$,3 components were determined at 20-keV intervals over the bombarding energy range. The experimental x-ray cross sections were found to be in reasonable agreement with those predicted by perturbed stationary-state (PSS) theory with relativistic (R), energy-loss (E), and Coulomb-deflection (C) corrections (ECPSSR).
