摘要
2018 年，在 Thomas Jefferson 国家加速器设施 (JLab) 进行了 E12-17-003 实验，旨在从氚气靶的重建缺失质量分布中探索可能存在的 nn 态 [K. N. Suzuki 等, Prog. Theor. Exp. Phys. 2022, 013D01 (2022), B. Pandey 等, Phys. Rev. C 105, L051001 (2022)]。作为该研究的一部分，还使用气态氢靶收集了数据，这不仅是为了精确的绝对质量尺度校准，也是为了研究 的电生。该数据集是在 (GeV/c)、 GeV 和 deg 下获取的。它涵盖了光生数据稀缺的前向角以及超核实验感兴趣的低 区域。另一方面，该运动学区域的 略高于先前的超核实验，从而为理解 超子电生微分截面随 的依赖关系提供了关键信息。本文报告了在 0.2-0.8 (GeV/c) 范围内 反应微分截面随 的依赖关系，并与目前可用的理论模型进行了比较。
