E. Piasecki et al., REACTION-MECHANISMS IN 24.3 MEV NUCLEON U-238 INDUCED REACTIONS THROUGH A COMPREHENSIVE STUDY OF FISSION/, Physics letters. Section B, 351(4), 1995, pp. 412-417
Nuclear reaction mechanisms for systems characterized by very differen
t asymmetries (U + C, Si, Ni, Au) have been investigated at 24.3 MeV/n
ucleon, using as observables both the fission products and the neutron
multiplicity. It is clearly observed that the fusion process - whatev
er its completeness - can only occur with rather light target nuclei,
indicating the persistence of potential energy effects much above the
interaction barrier.
