论文摘要
$^6 $ li（n，$γ$）$^7 $ li cross部分在中子能量范围为0.6至4 MEV，通过实施直接捕获形式主义的实施来衡量。这是通过通过实验测量$γ$过渡概率来完成的，并通过理论计算考虑了自旋因子。电磁过渡概率从$^7 $ li $^*$类似于$^6 $ li $+n $的初始中子捕获状态，是通过填充$^7 $ li li $^7 $ li（$ p，p'$ p，p'$^$^$^7 $ li $ $^*$反应的j $ _i $ li $^7 $ li的状态来衡量的。从捕获$γ$频谱中可以观察到共鸣状态的耦合在中子捕获中的中子分离阈值以上的偶联阈值的影响。通过{\ sc Fresco}和Talys-1.95直接捕获计算复制了测得的横截面。
The $^6$Li(n,$γ$)$^7$Li cross sections in the neutron energy range of 0.6 to 4 MeV have been measured by the experimental implementation of the direct capture formalism. This was done by measuring the $γ$ transition probability experimentally and accounting for the spin factor by theoretical calculation. The electromagnetic transition probabilities from $^7$Li$^*$ analogous to the initial neutron capture states of $^6$Li$+n$ were measured by populating the J$_i$ states of $^7$Li through $^7$Li($p,p'$)$^7$Li$^*$ reaction. The impact of coupling of resonant states, above neutron separation threshold of $^7$Li, in the neutron capture, is observed from the capture $γ$ spectrum. The measured cross sections were reproduced through {\sc fresco} and Talys-1.95 Direct Capture Calculations.
