Abstract: | The electron momentum distribution and Compton profiles of the rare earth
element Eu was measured using HPGe photon detector. The target atoms were
excited by means of 59.54 keV gamma rays from Am-241 radioactive source of
strength 300 mCi. Elemental foil of uniform aerial density, and purity
better than 99.9% was used as target. The data were recorded and analyzed
using a 4 K multichannel analyzer. These data duly corrected for instrumental
resolution effects, sample absorption, energy dependence of the differential
Compton cross-section and double scattering, and compared with theoretical
renormalized free atom (RFA) values. |
