Abstract
Precision measurements of the wavelengths of 1s2s 3S1-1s2p 3PJ transitions in ions of the helium isoelectronic sequence have recently been carried out with a view to testing QED in systems containing more than one electron. A critical review of the theoretical methods for calculating these energies is given in this paper and the one that follows. The authors demonstrate that relatively simple MCDF calculations can give high precision estimates of 23P fine-structure splittings.Keywords
