COULOMB ENERGY AVERAGED OVER THE NL(N)-ATOMIC STATES WITH A DEFINITE SIGN

摘要

A purely group-theoretical approach (for which the symmetric group plays a central role), based upon the use of properties of fractional-parentage coefficients and isoscalar factors, is developed for the derivation of the Coulomb energy averaged over the states, with a definite spin, arising from an atomic configuration nl(N).
