An analysis is made of the se&consistent random phase approxima%n (SC RPA) in whi& theground-state function satisfies the annihiIation corxlition. It is shown that the ground stE;te for a twoefectron system is identical with that obtained by a variational calculation including doublyexcited mnfiiura

## Abstract Detailed considerations of the groundβstate vector derived for the random phase approximation obtained earlier in a generator coordinate representation employing the unitary group parameter space reveal a particular correlated pair structure. The results of explicit calculations of grou
