最近有关滴线核晕结构的研究已经越来越多地引起实验和理论上的重视。研究表明,一些丰质子核具有一个或两个晕核子,而丰中子核有可能具有更多的晕核子形成晕中子集团。对晕核,其反应截面和核子逃逸截面相比于它的稳定的同位素要大的多,并且散射后形成碎片的动量分布宽度很 Recent studies on the drip line halo structure have increasingly attracted experimental and theoretical attention. Studies have shown that some abundance proton nuclei have one or two halo nuclei, while abundance neutrons may have more halo nuclei to form halo neutron groups. For nuclei, the reaction cross section and the nuclear escape cross section are much larger than its stable isotopes, and the width of the momentum distribution of the fragments formed after scattering is very large
