摘要：

We compute the energies and transition probabilities for low excitations in the one-dimensional antiferromagnetic spin-1/2 Heisenberg model by means of the recursion method. We analyse finite-size effects in the Euclidean time (tau-) representation and compare the resulting estimate for the thermodynamical limit with two parametrizations for the dynamical structure factors in the spectral (omega-) representation.
