Inclusion of core-unfreezing effects and orthogonality conditions in calculations of excited atomic states

  • 12 Accesses

Abstract

The 1s2s1S term of two-electron ions is used as an example to show that taking account of the relaxation of the atomic core under the excitation of an electron by going over to a frozen-in ion core is particularly effective if the one-electron functions cease to be orthogonal inside the excited configuration but the complete wave functions of the ground and excited states satisfy the orthogonality conditions.
