High-resolution measurements of the<i>K</i>-<i>MM</i>radiative Auger effect in medium-mass atoms

Abstract

High-resolution measurements of the K${\mathrm{\ensuremath{\beta}}}_{1,3}$ low-energy satellites of $_{42}\mathrm{Mo}$, $_{44}\mathrm{Ru}$, $_{46}\mathrm{Pd}$, $_{48}\mathrm{Cd}$, and $_{50}\mathrm{Sn}$ were performed. The photoinduced x-ray spectra were measured with a transmission-type bent-crystal spectrometer. Particular groups of K-MM radiative Auger effect (RAE) transitions could be identified. The intensity ratios I(K-MM RAE) / I(K${\mathrm{\ensuremath{\beta}}}_{13}$) were extracted. They are compared to relativistic Hartree-Fock theoretical predictions of Scofield. The experimental energies of the RAE edges are compared to calculated Auger transition energies. The present experiment provides experimental RAE results for solid elements with Z\ensuremath{\ge}42. \textcopyright{} 1996 The American Physical Society.
