摘要：

Nuclear relaxation in half-integer spin chains at low temperatures (TJ, the antiferromagnetic exchange constant) is dominated by dissipation from a gas of thermally excited, overdamped, spinons. The universal low-temperature dependence of the relaxation rates 1/T1 and 1/T2G is computed. © 1994 The American Physical Society.
