给出了由磁相互作用引起的NQR中自旋晶格驰豫的解，推广到ETA不为0的非轴晶场。他们找到了I=3/2的解析表达式，并给出了I=5/2、7/2和9/2的数值解。他们发现，松弛曲线随着ETA的变化而变化很大。给出了金属中费米接触和其他电子超精细相互作用引起的弛豫的具体结果。它们还描述了由附加磁场引起的变化，指出了标准核磁共振结果分解的区域。
The authors give solutions for spin-lattice relaxation in NQR due to magnetic interactions, generalized for non-axial crystal fields with eta not=0. They find analytic expressions for I=3/2 and give numerical solutions for I=5/2, 7/2 and 9/2. They 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. They also describe changes induced by the addition of a magnetic field, indicating fields at which standard NMR results break down.
