Relativistic effective charge model of a multi-electron atom

K. Dzikowski, O. D. Skoromnik, I. D. Feranchuk +2

A relativistic version of the effective charge model for computation of observable characteristics of multi-electron atoms and ions is developed. A complete and orthogonal Dirac hy…

A generating integral for the matrix elements of the Coulomb Green's function with the Coulomb wave functions

K. Dzikowski, O. D. Skoromnik

We analytically evaluate the generating integral $K_{n l} (β, β^{'}) = \int_{0}^{\infty} \int_{0}^{\infty} e^{- β r - β^{'} r^{'}} G_{n l} r^{q} r^{' q^{'}} d r d r^{'}$ and integral moments $J_{nl}(β, r) =…
