【摘要】 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 for129Xe in spin-exchange cells.
