Study of He Rabi nutations by optically-pumped cesium magnetometers
نویسندگان
چکیده
We describe a method for recording the Rabi nutation of nuclear spin polarized He by optically pumped cesium magnetometers. The measurement is performed by detecting the time-dependent magnetic field produced by the He magnetization. The observed signals are compared to theoretical models and the results are used to precisely trace the evolution of the magnetization. This procedure represents a convenient way to control and measure the Rabi flip angle and the degree of spin polarization in experiments using He magnetometers. The method requires only very coarse knowledge of the applied magnetic field’s magnitude.
