Abstract
X-ray form factors have been calculated for metallic vanadium by the APW method. The charge asphericity is estimated using ratios of the integrated intensities of the X-ray scattering for reflection pairs having the same value of sin( theta / lambda ). The charge asphericity obtained from a state-dependent potential, which was made to reproduce the dimensions and shape of the Fermi hole pocket at N-points, is larger than that obtained from state-independent potentials. The ratios of the integrated intensities obtained by the state-dependent potential are in reasonable agreement with the experimental ones determined by Weiss and Demarco (1965) and Diana and Mazzone (1974) and are in excellent agreement with a recent experiment performed by Ohba et al. (1981).
