Abstract
A fast reliable method is described for the calculation of the total di-electronic recombination rate coefficient alpha d(i;tot) of a ground-state He-like ion i. The equivalent-electron frozen-core approximation of Badnell (1984) is used to describe the three-electron problem. Electron exchange in the radial function of the spectator electron is allowed for by using the CEDW radial equations of Badnell (1983). A very accurate result for the total di-electronic recombination rate coefficient for a highly charged ion can be obtained from a single-configuration LS-coupling calculation if Aa<r and Aac24+ ion.Keywords
