N2 - In order to investigate the evolution of the GDR from low to high excitation energies, a series of experiments, in which high energy γ-rays were measured in heavy ion fusion reactions, have been performed at JAFRI and at RIKEN. It has been confirmed that the width of the GDR increases rapidly for Ex ≥ 100 MeV and our previously introduced Γ(Ex) can explain the data well for 80 ≤ Ex ≤ 120 MeV. The limiting temperature of the nucleus for existing of the GDR has been deduced for A ∼ 70, 105 and 130. The GDR seems to disappear at the temperature of about a quarter of the resonance energy.
