One-nucleon spectroscopic overlaps, their strength or spectroscopic factors (SFs), and nucleon removal cross sections for light nuclei in the mass range A≤12 were evaluated using the fully correlated Quantum Monte Carlo (QMC) wave functions (WFs). Harder (AV18+UX) and softer (NV2+3) bare interactions were used providing consistent results. The SFs were also taken from simple Shell Model (SM) calculations. This structure information was incorporated in the standard three-body Faddeev/Alt-Grassberger-Sandhas reaction formalism to evaluate the (p,pN) cross sections. The results further our understanding of the quenching of the quantum p-shell strength obtained from structure and reactions. We have found the ratios of the total QMC sums of SFs to the SM ones to be uniform and ∼ 3/4. The corresponding ratios of the sums Below Particle Threshold (BPT) of SFs, as well as of total cross sections, deviate strikingly from the uniform trend in some special cases. We find these ratios to be close to unit for Li9→8Li+n and C9→8B+p. In contrast, they are strongly reduced for C11→10C+n and B11→10Be+p mirror transitions, resulting from the quenching of the strength for low-lying 2+ final state transitions. The QMC theoretical cross section BPT for C11(p,pn) is about two times smaller than the experimental data.

轻外来原子核中量子 p 强度的淬灭


使用完全相关的量子蒙特卡洛 （QMC） 波函数 （WF） 评估了质量范围内 A≤12 中轻原子核的单核子光谱重叠、它们的强度或光谱因子 （SF） 以及核子去除截面。使用较硬 （AV18+UX） 和较软 （NV2+3） 的裸交互，提供一致的结果。SF 也取自简单的壳模型 （SM） 计算。该结构信息被纳入标准的三体 Faddeev/Alt-Grassberger-Sandhas 反应形式中，以评估 （p，pN） 横截面。结果进一步加深了我们对从结构和反应获得的量子 p 壳强度的淬灭的理解。我们发现 SF 的总 QMC 总和与 SM 总和的比率是均匀的，约为 3/4。在某些特殊情况下，SF 的低于粒子阈值 （BPT） 之和以及总横截面的相应比率与均匀趋势明显不同。我们发现这些比率接近 Li9→8Li+n 和 C9→8B+p 的单位。相比之下，C11→10C+n 和 B11→10Be+p 镜面跃迁的强度显著降低，这是由于低位 2+ 最终态跃迁的强度淬灭所致。C11（p，pn） 的 QMC 理论截面 BPT 比实验数据小约两倍。
