通过三种方法分析弹性α-$^3$H散射数据，确定$^7$Li$(3/2^-;0$ MeV)$\to \alpha+^3$H和$^7$Li$(1/2^-;0.478$ MeV)$\to \alpha+^3$H通道的渐近归一化系数，三种方法结果相似，还证实了镜像核ANC值的关系。
AI 中文摘要
通过使用三种不同方法分析弹性α-$^3$H 散射数据，分别确定了$^7$Li$(3/2^-;0$ MeV)$\to \alpha+^3$H 和$^7$Li$(1/2^-;0.478$ MeV)$\to \alpha+^3$H 通道的渐近归一化系数$C_{3/2}$和$C_{1/2}$。三种方法结果相似，平均 ANC 值为$C_{3/2}=2.08\pm 0.10$ fm$^{-1/2}$和$C_{1/2}=2.00\pm 0.10$ fm$^{-1/2}$。与$^7$Be 先前的 ANC 值比较，证实了镜像核 ANC 值的关系。
英文摘要
Asymptotic normalization coefficients (ANCs) $C_{3/2}$ and $C_{1/2}$ for the channels $^7$Li$(3/2^-;0$ MeV)$\to α+^3$H and $^7$Li$(1/2^-;0.478$ MeV)$\to α+^3$H, respectively, were determined by analyzing elastic $α^3$H- scattering data using three different methods. All three methods yield similar results. The ANC values averaged over the three methods are $C_{3/2}=2.08\pm 0.10$ fm$^{-1/2}$ and $C_{1/2}=2.00\pm 0.10$ fm$^{-1/2}$. Comparison of the found ANCs with the previously obtained ANCs for $^7$Be confirms the relationship linking the ANC values for mirror nuclei. This research on determining the ANCs for the $^7$Li nucleus is, to some extent, a continuation of the previously completed study on its mirror nucleus, $^7$Be [ D. A. Savin, L. D. Blokhintsev, B. F. Irgaziev, A. S. Kadyrov, and A. M. Mukhamedzhanov, Phys. Rev. C 112, 065807 (2025)].
