Simple analytic first-order wave functions corresponding to two-electron atoms electron correlation operators are
obtained by reduction of the Rayleigh-Schrödinger first order perturbation equation to that of one-electron through the partial
integration over the variables of one electron. The resulting first order wave functions are applied to evaluate the first order
expectation values of electron correlation operators associated with the radial correlation, magnetic shielding and diamagnetic
susceptibility. The results obtained have close agreement with other theoretical results.
