✦ Synopsis

Calculations on the ground states of the hellum isoelectronic series are carried out using variational wavefunctions of the form e (x .y), in which x and y are the combinations rl + rz f r,* occurring in the Coulomb Green's function. The results for helium are the most accurate to date using a two-variable wavefunction. accounting for 71.5% of the correlation energy.
