摘要
A simple form for the pseudo-potential is suggested for metallic sodium to investigate its properties. The computed values of the phonon frequencies in symmetry directions established an excellent accord with the measurements. A calculation of binding energy, compressibility and the elastic constants also highlighted the success of the proposed simple model- potential. © 1979.
