论文摘要
在84 MEV入射能量下,测量了13C(18O,16o)15C两中子转移反应的激发能光谱和绝对横截面角分布。该反应选择性地填充了残留核状态下的两种中子构型。精确的有限范围耦合反应通道计算用于分析数据。讨论了两种方法:极端簇和新引入的微观群集。后者利用了质谱幅度在质量参考框架中心,使用Moshinsky Transformation括号从外壳模型计算得出。结果很好地描述了实验横截面,并突出了涉及波函数中的群集配置。
Excitation energy spectra and absolute cross section angular distributions were measured for the 13C(18O,16O)15C two-neutron transfer reaction at 84 MeV incident energy. This reaction selectively populates two-neutron configurations in the states of the residual nucleus. Exact finite-range coupled reaction channel calculations are used to analyse the data. Two approaches are discussed: the extreme cluster and the newly introduced microscopic cluster. The latter makes use of spectroscopic amplitudes in the centre of mass reference frame, derived from shell-model calculations using the Moshinsky transformation brackets. The results describe well the experimental cross section and highlight cluster configurations in the involved wave functions.
