Cross-Section Profiles of Resonances in the Photoionization Continuum of Krypton and Xenon (600-400 Å)

Abstract

The cross-section profiles in krypton and xenon have been measured for one- and two-electron excitations of the type $n{s}^{2}n{p}^6\left({}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}\right)\to \mathrm{nsn}{p}^6\left({}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)mp$ or $n{s}^{2}n{p}^6\left({}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}\right)\to n{s}^{2}n{p}^4({}_{}{}^3{}_{}{}^{}P,{}_{}{}^1{}_{}{}^{}D,{}_{}{}^1{}_{}{}^{}S)ml{m}^{\prime }{l}^{\prime }$. These cross sections were assumed to have the form
