Description
Isospin may play an important role in light particle evaporation from hot composite
nuclei. On the basis of the statistical model, isospin effects on the evaporative
process are expected through two physical quantities: i) the isospin distribution
and ii) the symmetry energy. The first one is related to the level density parameter
a, while the second one affects the binding energy of the evaporated particles.
Statistical model calculations have been carried out in order to explore to what
extent these isospin effects can be observed experimentally, by measuring spectral
shapes, angular correlations and multiplicities of light particles as well as
evaporation residue distributions. We found that these observables are sensitive to the isospin, allowing to study the level density of exotic nuclei. We also report the results of a first experiment aimed at searching for isospin effects in the decay of 139Eu composite nuclei produced by a stable beam at Ex=90 MeV.
