通过监测机械化为磁力计的光泵铷系综的自旋极化，可以在混合惰性气体铷样品中观察到增强的惰性气体核磁共振信号。这些信号被认为是通过稀有气体-铷二元碰撞期间接触超精细相互作用的电子交换增强而产生的。惰性气体磁化的极化是通过与铷系综的自旋交换获得的。
Enhanced noble-gas NMR signals are observed in mixed noble-gas-rubidium samples by monitoring spin polarization of the optically pumped rubidium ensemble mechanized as a magnetometer. These signals are believed to arise through electron exchange enhancement of the contact hyperfine interaction during noble-gas-rubidium binary collisions. Polarization of the noble-gas magnetization is obtained through spin exchange with the rubidium ensemble.
