Abstract
A form for the relaxation shape function for a Heisenberg paramagnet is proposed which has the merit of satisfying certain sum rules and limits. It is shown by comparison with exact infinite-temperature calculations by Carboni and Richards, and inelastic neutron scattering measurements by Hutchings et al. on NMn, to provide a very good description of an antiferromagnetic linear chain at all temperatures.
