FOLD DISTRIBUTION ANALYSIS AS A TOOL FOR THE STUDY OF REACTION MECHANISMS AND ENTRY STATE POPULATION DISTRIBUTIONS AT HIGHEST SPINS

Gd (E = 238 MeV) reactions, measured with theγ-spectrometer GASP at LNL [2–4]. In the present work these investigationshave been extended to the Eu and Sm nuclei, which are populated in αypxnand ypxn reaction channels. Fold spectra, measured with the inner BGOball of GASP, have been obtained for the final nuclei by gating on discreteγ-lines representing transitions above isomers.We consider in this work a compound nuclear reaction mechanism. Theentry state population distributions have been simulated with the MonteCarlo code COMPA using a statistical theory [5]. Our previous investiga-tions [1] have shown that for the regarded compound nuclear reactions the
