✦ Synopsis

In the present paper we analyze the suppression mechanism of the (Zvfifl) amplitudes, in the framework of superfluid nuclear matter. We show that the interplay between spin-isospin modes and spin pairing vibrations in quenching the jj amplitude is particularly transparent in the context of the polarization propagator method. Our procedure is applied to finite nuclei of interest and our results are compared to other theoretical evaluations and to the experimental data. 0 1988 Academic Press. Inc.
