Electron momentum distribution and Compton profiles of tin

The Compton profile of Sn has been measured using a HPGe photon detector. The target atoms were exited by means of 59.54 keV gamma rays from 241Am radioactive source of strength 300 mCi. Elemental foil of uniform aerial density and purity better than 99.9% was used as target. The data was recorded and analyzed using a 4 K multichannel analyzer. The experimental data was corrected for instrumental resolution effects, sample absorption and energy dependence of the differential Compton cross-section. The Compton profiles measured in the present work for Sn constitute the first experimental report for 59.54 keV gamma rays scattered at 165 deg. The results are compared with theoretical Hartree-Fock free-atom profiles. (author)
