Abstract

A matrix method is used to calculate the energy eigenvalues and the corresponding orbital wave functions for a number of ³S states of the helium isoelectronic sequence within the framework of the 'fixed core' approximation. The wave functions are employed to calculate the expectation values of a number of one-electron operators. Results are presented for the 2 ³S, 3 ³S and 4 ³S states of He, Li⁺ and Be²⁺.
