在中子滴线之外:非束缚核的双中子衰变

Beyond the neutron-drip line: two-neutron decay of unbound nuclei

K. Hagino, H. Sagawa

摘要:

本文用一个核心核和两个价中子的三体模型讨论了中子滴线以外的非束缚核的衰变。我们特别讨论了价中子间的双中子关联在$^{26}$ O和$^{10}$ He核基态双中子发射中的作用。我们的计算清楚地表明,由于双中子关联,两个中子在背靠背方向上的发射增强。

英文摘要:

We discuss a decay of unbound nuclei beyond the neutron drip-line using a three-body model with a core nucleus and two valence neutrons. We particularly discuss the role of dineutron correlation between the valence neutrons in the two-neutron emission from the ground state of $^{26}$O and $^{10}$He nuclei. Our calculations clearly indicate that the emission of the two neutrons in the back-to-back direction is enhanced due to the dineutron correlation.
