摘要
在精心选择的动力学条件下，包容性电子散射可以隔离来自短程关联（SRC）中高动量核子的散射。SRC是由原子核中核子的硬、短程相互作用产生的，并且由于两核（2N）SRC源于所有原子核中相同的N-N相互作用，因此在SRC主导的 regime 中的横截面是相同的，仅相差一个整体缩放因子。这种缩放行为已被用于识别SRC的主导地位以及测量广泛范围内原子核中SRC的贡献。我们使用新获得的 H、H 和 He 数据，检验了这个缩放行为，发现相较于重型原子核，缩放区域得到了扩展。我们动机在此基础上，在可能发挥重要作用的三核SRC动力学条件下检视 H 和 He 数据。来自最大撞击核子动量的数据与三核SRC散射的隔离相符，并暗示在 He 中最高动量的核子几乎具有独立于夸克数的动量配置。
