Description

A method taking account of a deviation of state occupation numbers from the thermal RPA prescriptions is elaborated to study collective excitations in hot nuclei. The main idea of this Thermal Renormalized Random Phase Approximation goes back to Ken-Ji Hara and D.J.Rowe. In developing the TRRPA, a formalism of the thermofield dynamics (TFD) is used. Some numerical results are given for the SU(2) model. 15 refs., 1 fig
