摘要：

Two-electron atoms in screened and exponential cosine screened Coulomb potentials are studied. We have calculated within a Configuration Interaction approach, the ground and first excited states energies, and other mean values, for H- and Li+. We analyze their evolution with the screening parameters, and provide piactical fits which allow for a practical and rapid evaluation for plasma applications.
