Abstract
Using conformal invariance, the author shows that the nonuniversal exponent eta 0 associated with the decay of correlations along a defect line of modified bonds in the square-lattice Ising model is related to the amplitude A0= xi n/n of the correlation length/ at the bulk critical coupling Kc, on a strip with width n, periodic boundary conditions and two equidistant defect lines along the strip through A0=( pi eta 0)-1.Keywords
