By using Orthogonalised Plane Wave Pseudopotential we studied variation of superconducting transition temperature T_c with electron-phonon coupling (λ ) and Coulomb Pseudopotential (μ^*) of alkali metals. Unique opportunity taken to this method to investigate alkali metal for the purpose. Although the superconducting properties of the alkali metals are highly anomalous, these properties can still be understood within a conventional BCS framework where the electron pairing arises through the electron phonon interaction.
