Abstract
The spin-lattice relaxation rate 1/ and the spin-echo decay rate 1/ for the two-dimensional Heisenberg model are calculated using quantum Monte Carlo and maximum-entropy analytic continuation. The results are compared with recent experiments on , as well as predictions based on the nonlinear σ model.
