$^{48}$ Ca+ $^{96}$ Zr熔合反应中浅势的指示
Indications of a shallow potential in $^{48}$Ca+$^{96}$Zr fusion reactions
摘要：
通过耦合通道计算分析了$^{48}$ Ca+ $^{96}$ Zr的融合数据。通过施加在入口通道中具有浅口袋的电势，消除了先前分析的令人困惑的特征。因此，所观察到的聚变的$S$因子，在低能量下发展为最大值，可以相当好地再现。高能量数据也可以被解释，但这需要使用弱的、短程的虚势，该虚势吸收靠近势袋最小值位置的入射通量。在其他Ca+Zr系统的融合障碍的预测，并与以前已经开发的系统学进行了比较。
英文摘要：
Fusion data for $^{48}$Ca+$^{96}$Zr are analyzed by coupled-channels calculations. Puzzling features of a previous analysis are eliminated by applying a potential that has a shallow pocket in the entrance channel. Thus the observed $S$ factor for fusion, which develops a maximum at low energy, can be reproduced fairly well. The high-energy data can also be accounted for but that requires the use of a weak, short-ranged imaginary potential that absorbs the incoming flux near the location of the minimum of the potential pocket. Predictions of the fusion hindrance in other Ca+Zr systems are made and are compared with the systematics that has been developed previously.
