Abstract: The theoretical investigation of five superconducting slate piiran^iers (SSP) viz.eleciron-phonon coupling slrengili A, Coulomb pseudopotential /J* , transition temperature TV, isotope effective exponent «and iniferaction strength A^^Vof five monovalent (Li, Na, K, Rb and Cs), two divalent (Mg and Zn) and five polyvalent (In, Tl, Sn, Pb and Bi) metals have been carried out by our well-recognized and recently proposed model pseudopolential.We have employed here five different types of local field correction functions proposed by Huiircc, Taylor, Ichimaru-Uisumi, Land et al and Sarkar et al to study the exchange and correlation effects on the present computations.The recent local field correction functions due to Ichimaru-Ulsumi, Farid et al and Sarkar et al have been employed for the first tune in the study of SSP of metals.A very strong influence of all the exchange and correlation functions is found in the present study.Our results are in fair agreement with other available theoretical as well as experimental data.A strong dependency of the SSP of metals on the valency Z is found.
