Abstract：
Excitation functions have been measured for the dissipative reaction products at θ _l=26°and θ _l=42°in tEe 102 MeV to 108 MeV ¹⁹F ⁸⁺+ ⁴⁵Sc reactions by a step of 300 keV. The energy coherence widths and the dinuclear system lifetimes are extracted by analysing the cross section fluctuations. The dissipative reaction mechanisms are investigated.
