Abstract
The calculated transverse frequencies agree very well with the experimental results but there is some divergence at a few points in the longitudinal branches. The computed value of the electrical resistivity using the exchange and correlation gives a better agreement with experimental values than those obtained by other workers previously reported using the model potential. It has been observed that although the calculated numerical values of the resistivity differ noticeably when the two exchanges and correlations are used, the calculated phonon frequencies differ insignificantly. The disagreement between the calculated and experimental result is considered to be linked with the form of screening used.Keywords
