A linearised form for the screened form factors of electron‐ion interaction is proposed and applied for the prediction of superconducting state parameters viz. electron‐phonon coupling strength λ, Coulomb pseudopotential μ * , transition temperature T c , isotope effect exponent α, and the interaction strength N 0 V . Good agreement between the computed results, experimental data, and the results of Allen and Cohen based on the HA potential, supports the proposition.
