论文摘要
报告了使用相对自我吸收技术的激发$ 0^+_ 1 $状态的衰减宽度的直接测量。我们的$γ_{γ，0^+_ 1 \至1^+_ 1} = 8.17（14）_ \ Mathrm {stat。}（11）_ \ Mathrm {syst。} \ Mathrm {ev} $提供足够低的实验性不符号来测试现代核力量。将相应的过渡速率与基于手性有效田间理论的AB始于从头算的结果进行了比较，后者考虑到超出领先顺序的磁偶极子操作员的贡献。这可以进行精确测试，即以近代领先顺序输入的两体电流的影响。
A direct measurement of the decay width of the excited $0^+_1$ state of $^6$Li using the relative self-absorption technique is reported. Our value of $Γ_{γ, 0^+_1 \to 1^+_1} = 8.17(14)_\mathrm{stat.}(11)_\mathrm{syst.} \mathrm{eV}$ provides sufficiently low experimental uncertainties to test modern theories of nuclear forces. The corresponding transition rate is compared to the results of ab initio calculations based on chiral effective field theory that take into account contributions to the magnetic dipole operator beyond leading order. This enables a precision test of the impact of two-body currents that enter at next-to-leading order.
