【摘要】 在对中子晕核和质子晕核反应机制研究的基础上,经仔细分析和对比,进一步展现晕核反应机制和它的内部结构之间存在着内在的关系．计算结果分析表明,由于所选中子晕核11Li的结构比质子晕核23Al的结构更加松散,故与23Al比较,11Li更易碎裂,因而导致碎片多重性明显增加．同时由于11Li 的松散结构导致两体碰撞过程的减弱,因而导致动量耗散的减弱,故与23Al对比,将引起原子核阻止明显减少．更多还原

【Abstract】 It was based on the comparisons of the variance properties of fragment multiplicities FM’s and nuclear stoppings R’s for the neutron-halo colliding system with those of FZ’s and R’s for the proton-halo colliding system with the increases of beam energy in more detail, the closely correlations between the reaction mechanism and the inner structures of halo-nuclei is found. From above comparisons it is found that the variance properties of fragment multiplicities and nuclear stopping with the increases of beam energy are quite different for the neutron-halo and proton-halo colliding systems, such as the effects of loosely bound neutron-halo structure on the fragment multiplicities and nuclear stopping are obviously larger than those for the proton-halo colliding system. This is due to that the structures of halo-neutron nucleus 11Li is more loosely than that of the proton-halo nucleus 23A1 in this paper. In this case, the fragment multiplicity and nuclear stopping of halo nuclei may be used as a possible probe for studying the reaction mechanism and the correlation between the reaction mechanism and the inner structure of halo-nuclei.更多还原
