Additional non-Coulomb electron-electon interaction in multielectron systems
Vadim Kavera
The author suggests an approach based on the separation of total energy of multielectron systems into the semi-classical Coulomb part and the non-classical additional part. This ap…

Correlation energy of intrashell doubly excited states of heliumlike atoms
V. V. Kavera
The analysis of correlation energy of the simplest first approximation of a variational method for the intrashell states of two-electron atoms is the purpose of the present work. T…
