Effective operator method as a model of multiply charged ions

Autor: Vasiliy I. Sivtsev, Innokentiy S. Kychkin

Publikováno v: 9TH INTERNATIONAL CONFERENCE ON MATHEMATICAL MODELING: Dedicated to the 75th Anniversary of Professor V.N. Vragov.

The article suggests replacing the relativistic Hamiltonian of a many-electron atom (ion) with an effective operator. The matrix element of the latter with respect to the nonrelativistic wave functions in the LS-representation is equal to the matrix
