¹⁶O＋²⁴Mg反应全熔合激发函数的类共振结构

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.
