论文摘要
在这项研究中，我们分析了在Hartree-fock-Bogoliubov理论中描述的中子核散射中的入射中子电流如何通过按照电流，涡旋和入射中子中子循环进行数值计算来影响。我们发现，对入射中子通量的配对效应在粒子类型和孔型准粒子共振之间完全不同。在H型准粒子共振的情况下，配对起来可以防止中子通量进入细胞核，从而减少循环。在P型准粒子共振的情况下，配对可以减少低于共振能的能量的循环，但在高于共振能的能量下，配对对中子通量的影响是反向的，相反，循环增加了。
In this study, we analyzed how the incident neutron current is affected by the pairing effect in the neutron-nucleus scattering described within the framework of Hartree-Fock-Bogoliubov theory by performing numerical calculations in terms of current, vorticity, and circulation of the incident neutron current. We found that the pairing effect on the incident neutron flux is completely different between particle-type and hole-type quasiparticle resonances. In the case of h-type quasiparticle resonance, the pairing acts to prevent the neutron flux from entering the nucleus, reducing circulation. In the case of p-type quasiparticle resonance, pairing acts to reduce circulation at energies lower than the resonance energy, but at energies higher than the resonance energy, the effect of pairing on the neutron flux is reversed and, conversely, circulation is increased.
