Abstract
In this paper we calculate the finite-size corrections of an anisotropic integrable spin chain, consisting of spins s=1 and s=1/2. The calculations are done in two regions of the phase diagram with respect to the two couplings and . In case of conformal invariance we obtain the final answer for the ground state and its lowest excitations, which generalizes earlier results.
