| Popis: |
Nuclear states in Ni-56, at an initial excitation energy E*=70 MeV, were populated via the isospin T=0 reaction O-16+Ca-40. The dilepton- (e(+)e(-)) pairs and photon-decay yields were measured simultaneously. Statistical decay calculations describe well both measurements on an absolute scale. The isospin mixing parameter extracted from these measurements (alpha(2)=0.065) is consistent with other studies of the isospin symmetry in highly excited compound nuclei. The 1 sigma upper limit for the observed monopole strength is 4.3 nb, which is 3 times higher than the one sum rule value calculated with the statistical model for the decay of the compound nucleus. |
