Abstract

Nuclear relaxation in half-integer spin chains at low temperatures (T≪J, 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/

T_{1}

and 1/

T_{2 G}

is computed.
