Bound state solutions of the Schr\"odinger equation for the atomic systems interacting with the radial screened Coulomb potential: analytical approximation methods

We investigate the bound state properties of the hydrogen-like atoms in the radial screened Coulomb potential (RSCP). using three complementary analytical approaches - expectation values with Coulomb and Kratzer reference states, variational optimization with a scaled Kratzer basis, and the Hellmann-Feynman theorem - w...
