摘要：
We give solutions for spin-lattice relaxation in NQR due to magnetic interactions, generalized for non-axial crystal fields with eta-not-equal 0. We find analytic expressions for I = 3/2 and give numerical solutions for I = 5/2, 7/2 and 9/2. We find that the relaxation curves change considerably with eta. Specific results are derived for relaxation due to Fermi contact in metals and other electronic hyperfine interactions. We also describe changes induced by the addition of a magnetic field, indicating fields at which standard NMR results break down.
