Abstract
We consider an Ising chain with Hamiltonian , where the are independent random variables. We find a phase transition for . For the critical exponents exhibit mean-field classical behavior. Near we find a smoothly varying specific heat. We investigate the critical behavior near the upper and lower critical range by means of an expansion around .
