The experimental results of Ca-40 + Ca-48, Ca-40, Ti-46 reactions are reported. The comparison between gamma-ray spectra measured in coincidence with fusion evaporation residues for the three colliding systems shows a clear evidence of pre-equilibrium gamma-rays emission in the region around 10 MeV. BNV simulations also predict this emission. The saturation of GDR strength with temperature has been found with some dependence on the colliding system.

Abstract
The experimental results of Ca-40 + Ca-48, Ca-40, Ti-46 reactions are reported. The comparison between gamma-ray spectra measured in coincidence with fusion evaporation residues for the three colliding systems shows a clear evidence of pre-equilibrium gamma-rays emission in the region around 10 MeV. BNV simulations also predict this emission. The saturation of GDR strength with temperature has been found with some dependence on the colliding system.File in questo prodotto:
