Abstract
The exact solution of the spin chain model with exchange is found for twisted boundary conditions. The spectrum thus obtained can be reproduced by the asymptotic Bethe ansatz. The spectral flow of each eigenstate is determined exactly as a function of the twist angle. We find that the period for the ground state nicely fits in with the notion of fractional exclusion statistics.
