Measurement of 129Xe frequency shift due to Cs–129Xe collisions
【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.
