N2 - A matrix method is employed to calculate the energy eigenvalues and the corresponding orbital wave functions for a number of 1S states of the helium isoelectronic sequence. The 'inner' 1s-electron orbital is represented by a hydrogenic wave function, while the valence electron orbital is expanded in a complete set of Laguerre functions. Results are presented for the 1 1S, 2 1S and 3 1S states of He, Li+ and Be2+.
