ADITYA M. VORA1,*
Ashcroft’s empty core (EMC) model pseudopotential is used to study the residual resistivity of simple metals viz. Li, Na, K, Rb, Cs, Al, Pb as well as Al and Pb based dilute alloys. Three different types of local field correction functions proposed by Hartree (H), Taylor (T) and Ichimaru-Utsumi (IU) are used to investigate the effect of the exchange and correlation on the aforesaid property. The presently obtained results are compared with the other such theoretical and experimental data wherever exists. The comparison is highly encouraging. The investigation of the residual resistivity is found to be quite sensitive to the selection of the local field correction function, showing significant variation with the change in the function. Our conclusion suggests that similar study could be extended to other metallic elements and dilute alloys.
