Projected Hartree Product Wavefunctions. II. General Considerations of Young Operators

A discussion is given of the forms of two specific and one general Young operator for the irreducible representations of Sn important for fermion space functions. Comparisons are made of the projected Hartree product version of Lowdon's projected Hartree–Fock method with CI calculations.
