[en] The electronic charge density for Nb₃Ge and Nb₃Al is calculated using a self-consistent pseudopotential technique. Results indicate that there is charge transferred from Nb and Ge to the interstitial region, suggesting a metallic bonding description of these conpounds. The charge transfer from Ge to Nb is not prominent as suggested by the Bongi model. Calculated charge densities for states near the Fermi level suggest that R and M are more sensitive to atomic displacements along the chain than the points GAMMA and X chosen previously to explain A-15 Martensitic transitions
