Abstract

Abstract: The nuclear spin relaxation rate 1/T₁ of the laser-polarized ¹²⁹Xe produced in a low magnetic field was measured in a high magnetic field. The relations between the 1/T₁ and the pressure of N₂ or the temperature were obtained. The results show that the 1/T₁ increases as the pressure of N₂ varies from 0 to 11333.05Pa when the temperature was kept in 291K, and that the 1/T₁ decreases as the temperature varies from 234K to 292K when the pressure of N₂ was 1466.63Pa.

Key words: Laser-polarized ¹²⁹Xe, NMR measurement, Optically pumping, Relaxation
