Abstract

The quasi-particle-phonon model of pre-equilibrium decay (QP Ph M PED) is proposed. Within this model, intermediate states are specified by the number of quasi-particles, quasi-holes and phonons. In describing nuclear relaxation we consider two types of internuclear transitions with the change in exciton number byΔN ex=0, ±2 and number of phononΔN ph=±1. The mixed densities of intermediate statesϱ(N ex,N ph,E) have been determined. An analysis has been made of the structure of the hard part of the emission spectrum in the60Ni(p,p′) and120Sn(p,p′) reaction at ɛp=62 MeV. This analysis suggests the importance of taking into account the transitions withΔN ph=+1, along with the transitions withΔN ex= +2.
