Abstract
The generalized Sturmian method is applied to autoionizing states
of atoms and ions. If the Goscinskian basis sets allow for a sufficient
amount of angular correletion, the calculated energies of doubly-excited
(autoionizing) states are found to agree well with the few available
experimental energies. A large-Z approximation is discussed, and simple
formulas are derived which are valid not only for autoionizing states,
but for all states of an isoelectronic atomic series. Diagonalization
of a small block of the interelectron repulsion matrix yields roots
that can be used for a wide range of Z values.
