Collective motions in hot exotic nuclei: the finite temperature continuum-QRPA Original Research Article

The Finite Temperature Continuum-QRPA equations are derived in order to study collective motions in hot exotic nuclei. Such a formalism is consistently applied in coordinate space on top of Finite Temperature-HFB calculations, using the Skyrme interaction. The calculations are done for tin and oxygen isotopes. The pairing phase transition is found to be located around I MeV in120Sn and the low lying quadrupole response is strongly affected by the temperature. The GDR of136Sn is not modified by the temperature dependence. The dipole response of22O is also calculated with exact continuum treatment.
