DOI: 10.1002/qua.26653
Abstract: The first-order relativistic corrections to the non-relativistic energies of hydrogen-like atom embedded in plasma screening environments are calculated in the framework of direct perturbation theory by using the generalized pseudospectral method. The standard Debye-Huckel potential,… read more here.

DOI: 10.1140/epjd/e2020-10328-8
Abstract: The stability of two electron system under the influence of the exponential-cosine-screened-Coulomb (ECSC) potential has been studied as a function of continuously varying nuclear charge (Z) and screening constant (μ). Inter-electronic correlation has explicitly been… read more here.
