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
An algorithm for calculating excitation energies and transition moments in the randomphase approximation (RPA) of the polarization propagator is presented. The algorithm includes direct solution of the RPA eigenvalue problem and direct evaluation of products of superoperator Hamiltonian matrices wit
