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.
