极化核是核自旋研究和寻找标准模型之外的物理的有力工具。迄今为止，比较两个核物种的系统受到未知来源的异常但可重复的频率变化的限制。我们通过独立寻址、控制和测量核自旋极化各组分的影响，研究了He3-Xe129体系中的自相互作用。我们的研究结果直接排除了先前对这些变化的解释，并通过实验证明，它们可以通过物种依赖的自我相互作用来解释。我们还报道了Xe129在He3上引起的气相频移。
Polarized nuclei are a powerful tool in nuclear-spin studies and in the search for physics beyond the standard model. Systems which compare two nuclear species have thus far been limited by anomalous yet reproducible frequency variations of unknown origin. We studied the self-interactions in a He3-Xe129 system by independently addressing, controlling, and measuring the influence of each component of the nuclear-spin polarization. Our results directly rule out prior explanations of the shifts and demonstrate experimentally that they can be explained by species-dependent self-interactions. We also report a gas-phase frequency shift induced by Xe129 on He3.
