High-resolution study of heavy-ion-induced K<i>α</i>x-ray spectra of molybdenum atoms

Abstract

The K\ensuremath{\alpha} x-ray spectra of molybdenum bombarded with 6.7-MeV/u $^{4}\mathrm{He}$ and 5.5-MeV/u $^{16}\mathrm{O}$ ions were recorded with an on-line curved-crystal spectrometer in the DuMond geometry. The instrumental resolution was approximately 10.5 eV. K${\ensuremath{\alpha}}_{1}$${L}^{n=0}$,1,2,3 and K${\ensuremath{\alpha}}_{2}$${L}^{n=0}$,1 principal and satellite lines were observed and resolved for the first time for an atom in the mid-Z region. The relative yields, energies, and linewidths were determined. The yields in the $^{16}\mathrm{induced}$ spectrum deviate significantly from the binomial distribution. The width and energy shifts indicate additional multiple M-shell ionization.
