    • Abstract


      The complete electronic energy band structure of bcc potassium metal has been calculated using the non-relativistic augmented plane wave method. The density of states has been calculated and results compared with available thermal, optical and X-ray data. The lattice constant has been varied to get the band structures for pressures varying from 1 to 5 kb. The Fermi surface has been studied with varying lattice constants and the results discussed in the light of results of pressure-induced changes of de-Hass van-Alphen frequency obtained by Altounian and Datars.
