| Abstract: | The nuclear polarized 129 Xe gas by diode laser pumping was measured with a WP 80SY NMR spectrometer.We found that the SNR was greater than 100,and the signal enhancing factor was greater than 1000.After frozento solid state(80K),SNR was better than 50,the relaxation time was 4400s. |
