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 byNex=0, ±2 and number of phononNph=±1. The mixed densities of intermediate states(Nex,Nph,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 p=62 MeV. This analysis suggests the importance of taking into account the transitions withNph=+1, along with the transitions withNex= +2. |
