Abstract
FOLLOWING the success of the Wigner–Seitz cellular method1 for the calculation of binding energies of the alkali metals, a treatment for divalent metals was given by Herring and Hill2, who carried out detailed calculations for beryllium, taking into account the effect of the Brillouin zone boundaries. Recently, a simpler method has been used by Raimes3 for magnesium, and reasonable agreement with experiment was obtained. This communication presents the results of a new calculation for beryllium, similar to that of Raimes, undertaken with the object of ascertaining whether a simpler treatment could be applied to beryllium, and whether Raimes's suggestion regarding the correlation energy in the free atom would be satisfactory in this case.
