Abstract
Brillouin's theorem, together with a power series expansion method, is used to explain the result (obtained by the numerical calculations of other workers) that the use of a Hartree-Fock 1s orbital in the correlation splitting approach to two-electron atoms is less satisfactory than the use of a screened hydrogenic orbital.Keywords
