Abstract
The coupling between the nuclear shape dynamics and the internal degre es of freedom is investigated in the frame of a time-dependent Hartree -Fock-Bogolyubov Langevin formalism. The shape coordinate considered h ere is the quadrupole deformation, and the internal configuration spac e is restricted to the sd shell. The numerical results concern the eff ects of pairing, dissipation, and temperature on the giant quadrupole shape vibration of Si-28. Time scales for decay, thermalization,and co nfiguration transitions are obtained.
