摘要：

Bound s-state energies of an electron in the exponential cosine screened Coulomb potential, V(r) = -e2e-δrcos(δr)/r, are obtained analytically using the Ecker-Weizel approximation. For reasonable values of the screening parameter δ, the predicted results are in excellent agreement with the variational calculation of Lam and Varshni. The effect of screening on the shift of the quantum numbers from their normal values is also studied for various s-states. © 1979.
