Abstract

For the first time, an exact model potential calculation of the structural energies of Li, Na, Be and Mg is carried out without using any form of interpolation to avoid any possible error. The influences of using different model potential parameters and of applying effective mass approximation are examined. The observed HCP structure is found to have the lowest structural energy in all cases. Calculated and observed axial ratios are in good agreement.
