Abstract
In this paper, we have investigated the critical behavior of the ferro magnetic Ising model on union jack lattice. The model is equivalent to the eight-vertex model which can be solved as a free fermion model wi th the free fermion approximation. The critical exponents have been ob tained as alpha = alpha' = 0, beta = beta' = 0.125, gamma = gamma' = 0 .875 and delta = delta' = 8.
