An electron momentum spectroscopy investigation of the 4d core states of xenon

Abstract

We repon results for the first electron momentum specmcopy (EMS) investigation into the 4d5/2,3/2 core states of xenon.Experimental binding energy spedra were measured over the momentum range from 0.3 to 1.9 au with the derived 4d m s s section demonstrating the superiority of a distoed wave Eom approximation (DWBA) calculdion over the companding plane wave Eom a p p r o x i d o n (PWBA) calculation.The present result also indicated that the xenon Hamee-Fock (w) wavefunction may be inadequate, in that in its representation of the 4d ohital it was found to be not sufficiently diffuse in cwrdinate space.
