Abstract
The resistivities at constant volume and constant pressure and the volume derivative ( delta ln rho / delta lnV) were calculated over a range of temperatures (20K to melting) employing a fundamental calculation of the form factor and phonon spectrum. No parameters were adjusted to fit experimental data yet the agreement obtained with experiment was very good. The phonon frequencies were calculated using the recently-developed model potentials of Dagens et al. (1975) and the Geldart and Taylor (1970) screening. The form factors were calculated using the same model potential and screening but also incorporating the non-local electron-electron vertex correction of Rasolt (1975).
