Abstract

In the present paper, first ever experimental Compton profile of Nd₂O₃ have been measured using ¹³⁷Cs Compton spectrometer at an intermediate resolution of 0.34 a.u. Theoretical profile are computed using PP-DFT-GGA, PP-DFT- LDA and PP-DFT-SOGGA within the frame work of LCAO scheme in, and are compared with experimental results. Theoretical anisotropies in directional Compton profiles are explained in term of degenerate states along the Fermi level.
