A COMPTON PROFILE STUDY OF POLYCRYSTALLINE RHENIUM

In this paper the results of the first study on the Compton profile of polycrystalline rhenium are reported. The measurements have been made using 59.54 keV gamma-rays. To interpret the data, the renormalized-f ree-atom (RFA) model has been employed taking several 5d-6s configurat ions. Best agreement between theory and experiment is found for 5d(6)6 s(1) valence electron configuration. The data show surprisingly good a greement with the relativistic APW Compton profile of the isoelectroni c metal technetium. This confirms similes electronic structures for rh enium and technetium metals.
