^(16)O+^(28)Si全熔合激发函数

Measurement of the Complete Fusion Excitation Function for the ^(16)O+^(28)Si Reaction

在50—90 MeV的能量范围内,以1.0 MeV为能量步长,测量了^(16)O+^(28)Si的全熔合激发函数。用熔合模型分析了激发函数,提取了模型参数在质心系能量小于46MeV时,激发函数存在粗结构,其峰位分别在34.5、38.5和43MeV。能量在46MeV以上时,结构逐渐消失。

The complete fusion excitation function for the ^(16)O+^(28)Si reaction is measured in the range of 50—90 MeV with step of 1.0 MeV. It is analysed by using some theoretical models and the model parameters are extracted from this analysis. Gross s.tructure is found in the excitation function when E_(CM)<46MeV. The energies of peaks are 34.5, 38.5 and 43.0 MeV, respectively. The structure vanishes gradually when E_(CM)>46.0MeV.
