| Abstract: |
Study of the electronic state in -Ga using Compton
scattering technique is reported in this paper. The isotropic Compton
profile has been measured using a  -ray
Compton
spectrometer, which employs a 5 Ci annular 241Am source. The
measurement is compared with the available augmented plane-wave (APW) and
non-local model potential calculations. Comparison with the present calculations
based on renormalised-free-atom (RFA) model for 4s and 4p electrons is also
made. It is seen that APW (with Lam-Platzman electron-electron correlation)
calculation is in better agreement with the experiment. The Fourier transform
of experimental Compton profile confirms the
free-electron like behaviour of Ga.
