Abstract
In this paper we calculate the finite-size corrections of an anisotropic integrable spin chain, consisting of spins s = 1 and . The calculations are done in two regions of the phase diagram with respect to the two couplings and . In the case of conformal invariance we obtain the final answer for the ground state and its lowest excitations, which generalizes earlier results.Keywords
