Abstract：
The Angular distribution and excitation function of the disspative products have been measured in the reaction ¹⁹F+⁹³Nb. The reaction time of the dissipative products is extracted from the angular distribution and compared with that extracted from their energy auto-correlation function. A great difference exists between the reaction times extracted from these two methods. The results obtained from analyzing these two methods in different symmetrical reaction systems show that the reaction time extracted in the more symmetrical system by analyzing the slope of the angular distribution demonstrates the characteristic times of both direct and dissipative products, while the reaction times extracted in the more asymmetrical system only reflects the character of the direct products. But the method of the energy auto-correlation function can give the characteristic time for dissipative products in both symmetrical and asymmetrical system. In addition, the damping rotation feature of the dinuclear system formed in the dissipative reaction can be described by analyzing the energy auto-correlation function.
