We present the electron momentum densities of TiAl , Ti3Al and TiAl3 alloys in terms of Compton profile. Compton profiles (CP) of Ti and Al metals were calculated by adopting the renormalized free atom (RFA) and free electron models and choosing (3d3 – 4s1) configuration to Ti and (3s2 – 3p1) to Al as best electron configurations. The Compton profiles values were obtained by the Superposition model for the three intermetallic alloys. The theoretical results were compared with the experimental values. The present work results of TiAl , Ti3Al and TiAl3 alloys are in good agreement with the experimental values.
In this paper we used renormalized free atom model to study the electronic configuration of vanadium carbide compound. The theoretical values were obtained after finding the values of each element separately and using the superposition model to find the best electronic arrangement. These results were compared with experimental values measured by using high energy (661.65 keV)ɣ-radiations from a 137Cs source. We observed two things, first; if half the density of the electronic momentum of the compound is concentrated in vanadium we get the electronic order (2s1-2p1.5)C+(3d+5.5-4s1)V. second, if full the density of the electronic momentum of the compound is concentrated in vanadium we got the electron order (2s1-2p0)C+(3d+7-4s1)V .The best results out of these were when the full electron transfer from carbon to vanadium occurs.
