Abstract

Collective pairing excitations in superfluid nuclei are studied by using the semiclassical time-dependent Hartree-Fock-Bogoliubov equations of motion in a linear approximation. It is found that the strength function associated with the semiclassical anomalous density response function has a resonance structure with a sharp peak around double energy gap that displays the monopole pairing collective mode.
