论文摘要
由于通过许多可能的反应通道进行建设性干扰，增强性发生在两种中子的传输反应中，从结合系统$ a $ $ a $到弱结合的系统（$ a $+2）（每当中间系统都没有结合并且由与共振状态的连续体组成时。在$^6 $ HE的情况下，我们阐明了这一现象，该现象在中间$^5 $ He核的轨道中以两个中子为模型，将未结合（$+1）系统的现实情况与人工绑定的情况进行了比较。在这些计算中，正确建模的连续体被认为至关重要，并且由于配对相关性而导致显着增强。
Enhancement, due to constructive interference through the many possible reaction channels, occurs in two-neutron transfer reactions from a bound system $A$ to a weakly-bound system ($A$+2), whenever the intermediate system is unbound and consists of a continuum with a resonant state. We elucidate this phenomenon in the case of $^6$He, modeled as two neutrons in the orbitals of an intermediate $^5$He nucleus, comparing the realistic case of an unbound ($A$+1) system with an artificially bound case. A properly modeled continuum in these calculations is found to be crucial and leads to significant enhancement due to pairing correlations.
