Abstract

The first order Hartree–Fock equations of the 1__s__2__p__3__s__ ^4^P^0^ state of the three‐electron atomic systems have been solved exactly. These solutions are used to evaluate Hartree–Fock energy up to third order with high accuracy. The third order Hartree–Fock energies for Li to Ne^7+^ are compared with those derived from experiment and other theoretical calculations.
