The electron-electron interaction in doubly-excited states of atoms
Doubly-excited states of the isoelectronic sequence of H-, in which both electrons are in high principal quantum numbers, are examined on the basis of alternative pictures of the correlations between the two electrons. Restricting ourselves to the lowest1 S states with both electrons in principal quantum number n, we parametrise the electron-electron interaction on the basis of these pictures and compare the resulting simple expressions with more elaborate numerical calculations. This provides further understanding of the nature of correlations in such states. © 1984 Indian Academy of Sciences.
