Abstract：
The excitation functions have been measured for the dissipative products in ¹⁹F+⁴⁵Sc reaction from 102 MeV to 108 MeV in 300 keV steps at θ_l=26° and θ_l=42°. The thickness of the self-supporting ⁴⁵Sc target is 53 μg/cm². The energy coherence width T for each element measured is extracted and the corresponding dinuclear system lifetime is also deduced by the advanced Ericson statistical theory. The dissipative reaction mechanism is discussed.
