Abstract:

A theoretical study is made on the mechanism of the nuclear magnetic spin-lattice relaxation in solid ortho-hydrogen below T_λ. The predominant mechanism assumed is the inelastic scattering of the rotational excitation waves by the nuclear magnetic moment of ortho-hydrogen. The calculation of the thermal transition probability and relaxation time T₁ is carried out following the same line as in the case of antiferromagnetics. The temperature dependence of T₁ is obtained numerically. The result shows that T₁≃10 ∼100 sec at T_λ.
