Correlated Atomic Pair Functions by the - Method . I . Ground State 1 J S and Lowest Excited States


Some low n 1 S and n 3 S states of the helium atom are computed with the aid of the e~ method which formulates the electronic wave function of the 2 electrons as = e~F, where q = Z(r\ + r2) \ r \ 2 and here Z = 2. Both the differential and the integral equation for F contain a pseudopotential V instead of the true potential V that contrary to V is finite… (More)
