摘要：

We have measured the longitudinal nuclear relaxation rate T1-1 for He3 in the presence of molecular oxygen in the temperature range T200-400 K. At room temperature, T1-1=0.448±0.010 s-1 per amagat O2, in approximate agreement with theoretical models for intermolecular dipolar relaxation. Furthermore, in this temperature range, T1-1T-0.42±0.04. Our results are of practical importance for the growing number of applications involving hyperpolarized noble gases. © 1995 The American Physical Society.
