论文摘要
使用反对称分子动力学研究了嵌入在32S激发态的α+28SI和16o+16o分子状态的性质，并可能对恒星反应产生影响。从簇光谱因子的分析中，α+28SI和16o+16o分子状态的候选物被鉴定在簇阈值阈值能量附近和之上。 Alpha+28SI分子状态的计算特性与α+28sonant散射实验报告的特性一致。另一方面，预测的16o+16o分子状态与32s的超级形式相同，与Alpha非弹性散射实验提出的分配相矛盾。我们的计算表明，单极从基态到16o+16o分子状态的过渡相当弱，并且不会因α非弹性散射而强烈激发。
The properties of the alpha+28Si and 16O+16O molecular states which are embedded in the excited states of 32S and can have an impact on the stellar reactions are investigated using the antisymmetrized molecular dynamics. From the analysis of the cluster spectroscopic factors, the candidates of alpha+28Si and 16O+16O molecular states are identified close to and above the cluster threshold energies. The calculated properties of the alpha+28Si molecular states are consistent with those reported by the alpha+28Siresonant scattering experiments. On the other hand, the 16O+16O molecular state, which is predicted to be identical to the superdeformation of 32S, is inconsistent with the assignment proposed by an alpha inelastic scattering experiment. Our calculation suggests that the monopole transition from the ground state to the 16O+16O molecular state is rather weak and is not strongly excited by the alpha inelastic scattering.
