ITERATION OF THE SCHRODINGER-EQUATION STARTING FROM HARTREE-FOCK WAVE-FUNCTIONS

Methods are discussed for iterating the many-particle Schrodinger equation starting from Hartree-Fock wave functions. It is shown that when the Hartree-Fock wave function is expressed as a linear combination of the appropriate basis functions in hyperspherical coordinates the hyperangular integrals needed for iteration can be evaluated analytically. It is also shown that the first-iterated solutions contain terms corresponding to angular correlation.
