Au L x-ray relative intensities induced by proton impact.

Abstract

Theoretical intensity ratios of the L\ensuremath{\beta}, L\ensuremath{\gamma}, L\ensuremath{\eta}, L${\ensuremath{\gamma}}_{1}$, and L${\ensuremath{\gamma}}_{2,3,6}$ to the L\ensuremath{\alpha} line induced by proton impact on gold have been calculated from various L-subshell databases in the proton energy range 0.18--10 MeV. Good agreements are obtained between the measurements and the ratios computed by using the decay yields we present and the ionization cross sections by Cohen and Harrigan [At. Data Nucl. Data. Tables 33, 255 (1985)]. The latter were calculated in the plane-wave Born approximation with corrections for energy loss, Coulomb deflection, perturbed stationary state, and relativistic effects. The L-subshell coupling effects are not found.
