The proton spin-lattice relaxation time tl has been measured in H2 gas as a function of (a) density at 20.4°K, (b) ortho-para concentration at 20.4°K, (c) percentage H2 molecules in H~-He mixtures at 20.4°K, (d) density of the saturated vapour between 20.4°K . and 15:5°K. The results are interpreted

The proton spin relaxation time tl for H2 liquid has been measured as a function of temperature and otho-para concentration. For normal H2, tx is found to be 0.18 second at 20.4°K and is found to increase with decreasing temperature and decrease with decreasing ortho-H2 concentrations. Calculations
