摘要
测量了１０２ＭｅＶ到１０８ＭｅＶ（１９）Ｆ＋（４５）Ｓｃ反应在θ１＝２６°和θ１＝４２°的耗散部分产物的激发函数，能量步长３００ｋｅＶ，靶厚５３μｇ／ｃｍ２．用统计理论求得了各元素的能量相干宽度Γ，提取了反应的特征时间τ，探讨了耗散反应机制．
Excitation functions have been measured for the dissipative reaction products at θl= 26° and θl= 42° in tEe 102 MeV to 108 MeV 19F8+ + 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.
