我们对晕核的候选者F的结构进行了详细的分析。用三体波函数F +n+ n计算了半径和反应总截面，讨论了中子对与单粒子能量的竞争如何引起F的结构变化。本分析进一步阐明了一个新的方面的反晕效应，抑制晕结构在基态。
We perform a detailed analysis for the structure ofF, which is a candidate of the halo nucleus. We calculate the radius and total reaction cross section using a three-body wave function ofF+n+nand discuss how the competition between the neutron-pairing and the single-particle energy induces structural changes ofF. The present analysis further clarifies a new aspect of the anti-halo effect that suppresses the halo structure in the ground state.
