本文对吸附在玻璃细胞表面的131个~（13）C原子的核自旋弛豫进行了定量研究。通过使用高度不对称的玻璃细胞，我们已经增加了壁诱导的四极分裂的核自旋子级的131个原子的近两个数量级，比以前报道的值。这些大的表面相互作用被用来提取关于吸附在玻璃表面上的131个氘原子的原子核所经历的电场梯度和关于表面吸附的活化能的定量信息
We have made a quantitative study of nuclear spin relaxation of 131 Xe atoms adsorbed on the surface of glass cells. By using highly asymmetric glass cells we have increased the wall-induced quadrupole splitting of the nuclear-spin sublevels of 131 Xe atoms by almost two orders of magnitude over previously reported values. These large surface interactions were used to extract quantitative information about the electric-field gradients experienced by the nuclei of 131 Xe atoms adsorbed on the glass surface and about the activation energies for surface adsorption
