Description
I will present results concerning the effects of particle-vibration coupling (PVC),
a topic to which Ikuko Hamamoto gave fundamental contributions.
I will discuss how to determine the PVC strength, in particular through
the study of multiplet splittings.
I will then present quantitative microscopic calculations of the
strength function associated with pairing modes in A+2 nuclei
going beyond the RPA by including the coupling to collective excitations of
closed shell A core, including continuum effects. The formalism accounts both
for single-particle self-energy effects and for the pairing interaction
induced by phonon exchange. Such studies are relevant for the experimental searches of
collective high-lying pairing vibration, whose existence was predicted
but not yet experimentally confirmed.
