计算给出了价核子在核外部分布的概率和贡献，以此作为晕核态的判断标准。
The outside probabilities and contributions of valence nucleons given by these calculations are considered as the criterion of halo states.
结果显示12B第二、三激发态为单中子晕核态，这是在B稳定线附近找到的第二个核新的晕核态。
The results show that the second and third excited states of 12B are one-neutron halo states. It is the second nucleus to be found with new halo states near the p stable line.
通过研究均方根半径随结合能变化的规律，指出了晕核态存在的条件，尤其是质子晕核态存在的条件。
By studying the variation of root mean square radius with the separation energy, conditions for the existence of halo states are pointed out, especially of the proton halo states.
