Abstract

We have applied the variational perturbation (HSK) procedure to the 1s3s ³S state of the helium isoelectronic sequence. The nonrelativistic energies and corresponding total wavefunctions have been determined with estimated errors less than 5 parts in 10¹⁰ and one part in 10⁴, respectively, for all Z≥2. For He in particular we report the value E = −4.13737 81348 Rh, and correspondingly for Li⁺, E = −9.50415 29115 Rh. The values quoted are the best converged results for these states reported so far. We present the numerical results in tables and illustrative figures.
