Title: Isospin fragmentation of pairing vibrations

Abstract

The random-phase-approximation formalism with good isospin, developed previously for the particle-hole excitations, is extended to the two-particle and two-hole excitations. It is found that the effect of the isospin symmetry on the normal pairing vibrations is of minor importance. In contrast, the giant pairing vibrations are always split among the isospin components. As an illustration we discuss the experimental results for the /sup 112/Sn(/ital p/,/ital t/) reaction.
