Electronic structure of gadolinium and dysprosium using compton scattering technique

Abstract

In this paper we present the first ever measured Compton profiles of polycrystalline gadolinium and dysprosium using 661.65 keV gamma-rays. The Compton data are compared with renormalized-free-atom (RFA) and free-electron model profiles. In both cases the RFA model (with e-- e -correlation) gives a better agreement with the experiment. The hybridization effects of s-, p-, d-, and f-electrons are discussed, using the first derivatives of the Compton profiles. We also report the cohesive energy of both samples, computed from the RFA calculations. - PACS numbers: 13.60.F, 71.15.Nc, 78.70. -g, 78.70.Ck © 2006 Verlag der Zeitschrift für Naturforschung.
