Abstract
We obtain the exact Bethe ansatz solution of an O(n) model on the honeycomb lattice with open boundaries across a finite strip. Several quantities relevant to the surface critical behaviour of the O(n) model are derived from this solution, The exact surface critical exponents are in agreement with those obtained by Cardy and by Duplantier and Saleur based on conformal invariance arguments.
