质子晕核的增强亚垒熔合

Enhanced subbarrier fusion for proton halo nuclei

Raj Kumar, J. A. Lay, A. Vitturi

摘要:

本文用一个简单的模型来描述弱束缚核的亚势垒熔合中的破裂过程的动力学效应。我们模拟两个类似的情况下,涉及中子或质子晕核,都示意性地耦合到分裂通道。我们发现,库仑势垒的质子分裂通道的减少导致,其他条件相同,一个更大的增强亚钡聚变概率相对于中子晕的情况。

英文摘要:

In this short note we use a simple model to describe the dynamical effects of break-up processes in the subbarrier fusion involving weakly bound nuclei. We model two similar cases involving either a neutron or a proton halo nucleus, both schematically coupled to the break-up channels. We find that the decrease of the coulomb barrier in the proton break-up channel leads, ceteris paribus, to a larger enhancement of the subbarier fusion probabilities with respect to the neutron-halo case.
