Abstract:
A Wigner-Seitz cell dependent 'relaxed core' model pseudopotential is developed
from first principles consideration of the stationary state perturbation theory and the free
electron gas approximation. The Fourier transform of the local potential is evaluated and
applied within existing theoretical frameworks in calculating the form factors, binding
energy, monovacancy resistivity and paramagnetic spin susceptibility of metals under a
scheme that requires no fittings to experimental data. In all these calculations, the
screening due to the electron gas is accounted for through the modified Hartree dielectric
function. The results obtained in these calculations are in good agreement with
experimental values and show a general improvement on the results of previous
researches.
