Abstract:
The study of the collective properties of a nuclear system is a powerful
tool to understand the structure which lies inside the nucleus. A successful
technique which has been used in this field is the measurement of the
-decay of the highly collective Giant Dipole Resonance (GDR). In fact,
GDR can be used as a probe for the internal structure of hot nuclei and,
in addition, constitutes a clock for the thermalization process. Using the
fusion–evaporation reaction, it has been recently possible to study (i) the
yield of the high-energy
-ray emission of the Dynamical Dipole which
takes place during the fusion process and (ii) the degree of isospin mixing
at high temperature in the decay of 80Zr. In the first case it is important
to stress the fact that the predictions of the theoretical models might
differ depending on the type of nuclear equation of state (EOS) and on
the N–N in-medium cross-section used in the calculations while, in the
second physics case, the data are relative to the heaviest N = Z nucleus
which has been possible to populate in the I = 0 channel using fusion–
evaporation reaction. Both experiments were performed at the Laboratori
Nazionali di Legnaro using the HECTOR-GARFIELD array. The highenergy
-rays were measured in coincidence with light charged particles
and fusion–evaporation residues.
