Abstract
The response functions for the extended second and third random phase approximation are compared. A second order perturbation calculation shows that the first-order amplitude for the direct 3p3h excitation from the ground state cancels with those that are engendered by the 1p1h-3p3h coupling. As a consequence nonvanishing 3p3h effects to the 1p1h response involve off energy shell renormalization only. On shell 3p3h processes are absent.
