Exciton number dependence of the Griffin model two-body matrix element

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The exciton number dependence of the residual two-body matrix element has been determined using published particle-hole pair creation rates obtained from semi-phenomenological calculations. The previous energy dependence of the mean squared matrix element has been replaced by a dependence on the average excitation energy per degree of freedom,E/n. ForE/n less than 7 MeV or greater than 15 MeV, the form of the energy dependence has been slightly modified. These changes result in a factor of three reduction in the predicted Griffin model composite nucleus equilibration times but in only minor changes in the calculated energy spectra for emitted particles.
