Abstract
We report here the s ā d electron transfer and superconductivity in Barium under pressure. The bandstructure was done by Linear Muffin-Tin Orbital method at zero and 40kbar pressures. The density of states at the Fermi energy N(EF) and the number of state functions n(EF) were calculated using the Tetrahedron method. It was found that the d-electron number increases from 0.86 to 1.06 as pressure increases from 0 to 40kbar, as predicted by Wittig so that the metal becomes a pressure induced superconductor.
