用三体模型对晕核的熔合反应进行了理论研究。用含时波包方法求解三体薛定谔方程。晕核子的动力学在坐标空间中可视化。中子晕和质子晕系统之间的显着差异进行了讨论，在库仑破裂过程。计算了Be-11 - Bi-209和He-6 - U-238的熔合截面。我们的计算表明，弱束缚中子的存在会稍微阻碍聚变截面。目前的结果很好地同意最近的测量。
Fusion reactions of halo nuclei are investigated theoretically with a three-body model. The time-dependent wave-packet method is used to solve the three-body Schrodinger equation. Dynamics of the halo nucleons are visualized in the coordinate space. Significant differences between the neutron-halo and the proton-halo systems are discussed in connection to the Coulomb breakup process. The fusion cross sections are calculated for Be-11 - Bi-209 and He-6 - U-238. Our calculation indicates that the fusion cross section is slightly hindered by the presence of weakly bound neutrons. The present results nicely agree with recent measurements.
