Abstract
A convenient approximate prescription for studying the interplay between dielectric polarisation effects and the relaxation of outer-shell electrons towards a deep core hole is tested for the case of 3d photoabsorption in xenon. The authors adapt the methods of Amusia and co-workers (1980) to a newly developed relativistic time-dependent local density approximation (RTDLDA). The natural choice of a Slater transition-state potential for the RTDLDA calculation produces nearly quantitative agreement with recent absolute cross section data.Keywords
