英文摘要 | Radiation damping is generally observed when a sample with high spin concentration and high gyromagnetic ratio is placed in a high magnetic field. However, we firstly observed liquid-state Xe-129 radiation damping with laser-enhanced nuclear polarization at low magnetic field in a flow system in which the polarization enhancement factor for the liquid-state Xe-129 was estimated to be 5000, and, furthermore, theoretically simulated the envelopes of the Xe-129 free induction decay and spectral lineshape in the presence of both relaxation and radiation damping with different pulse flip angles and ratios of T-2(*)/T-rd. The radiation damping time constant T-rd of 5 ms was derived on the basis of the simulations. The reasons of depolarization and the further possible improvements were also discussed. |
