Resonance-like Structure of Complete Fusion Excitation Function for 16O+24Mg Reaction
-
摘要: 本工作用位置灵敏的△E-E望远镜系统,入射能量步长为1.0MeV,测量了55~90MeV~(16)O+~(24)Mg反应全熔合激发函数.实验结果表明,这个反应的全熔合激发函数不是平滑的,存在着宽结构.峰位在E_CM=34.2、37.8、40.6、43.8和46.6MeV.当E_CM>48MeV时,激发函数的结构消失了。 The complete fusion excitation function for the 16O+24Mg reaction has been measured in the energy range of 55~90MeVwith the step of 1.0MeV using a position sensitive△E-E telescopy system. It shows that the fusion excitation function is not smooth and exhibits gross structure. Peaks are at ECM=34. 2, 37. 8,40. 6,43. 8 and 46. 6MeV. The resonancestructure of the excitation function vanishes when ECM is>48.0MeV.Abstract: The complete fusion excitation function for the 16O+24Mg reaction has been measured in the energy range of 55~90MeVwith the step of 1.0MeV using a position sensitive△E-E telescopy system.
