首次测量了表征~(129)Cs NMR和EPR频移的增强因子κ0。在100 nT的低磁场下,用核磁共振频移法测得80 °C和90 °C时的增强因子κ0分别为(702±41)和(653±20)。这一结果对预测自旋交换池中Cs的EPR频移和~(129)Sr的NMR频移是有用的。
Enhancement factor κ0, which characterizes NMR and EPR frequency shifts for Cs—129Xe, is measured for the first time. The enhancement factor κ0 was measured to be (702±41) at 80 °C and (653±20) at 90 °C, using the NMR frequency shift, detected by atomic magnetometer at a low magnetic field of 100 nT. This result is useful for predicting the EPR frequency shifts for Cs and the NMR frequency shifts for 129Xe in spin-exchange cells.
