Phys. Rev. 122, 359–366 (1961)Higher Random-Phase Approximations in the Many-Body ProblemReceived 4 November 1960; published in the issue dated April 1961 The usual random-phase approximation combined with an equations-of-motion technique for the many-electron problem is extended, yielding many of the known results of series summation methods in a straight-forward manner. The method should apply to other types of many-body problems as well. © 1961 The American Physical Society URL:
