Abstract
The two-point spin-spin correlation function of the weakly disordered Baxter model in the phase transition point is calculated. The corresponding critical exponent appears to be zero, i.e. the decay of the correlation function is slower than the power law: R- eta . Together with the previous result that the specific heat critical exponent of the weakly disordered Baxter model is also universal: alpha -0, it gives the complete set of universal critical exponents which describe the phase transition. The critical exponents of the weakly disordered Baxter model coincide with those of the weakly disordered Ising model.Keywords
