Abstract: A new exponent characterizing the rounding of crystal facets is found by mapping a crystal surface onto the asymmetric six-vertex model (i.e. with external fields h and ) and using the Bethe ansatz to obtain appropriate expansions of the free energy close to criticality. Leading order exponents in, are determined along the whole phase boundary and in an arbitrary direction . A possible experimental verification of this result is discussed.
