The measurements of the gamma decay from the giant dipole resonance (GDR) at finite temperature and far from stability is used to obtain information on the properties of the nucleus. The study of the gamma decay from the giant dipole resonance (GDR) at finite temperature and far from stability allows to obtain information on the properties of nuclei in different regimes. Exclusive measurements of gamma-decays with fusion reactions were made at LNL (INFN) and GSI in order to address 2 different physical problems. First, the measurement of the temperature dependence of the GDR width up to T = 4 MeV in the mass region A = 130 will be shown together with its interpretation in terms of thermal shape fluctuations calculations. Secondly, the search for the pygmy dipole resonance in neutron rich {sup 68}Ni nucleus produced by fragmentation at GSI will be presented. Coulomb excitation at 600 MeV/nucleon was employed and the gamma-rays were detected with the RISING array.
