Abstract
The Heisenberg antiferromagnetic chain of spin 1 with the most general single ion anisotropy is numerically analyzed. Chains of length up to 22 sites are studied by a Lanczos method and up to 32 sites with a qu antum Monte Carlo. Gaps, magnetic excitations, dynamical properties an d magnetic field behaviour are obtained. The recent neutron scattering experiments on the quasi one-dimensional antiferromagnet NENP are ful ly explained by our results.
