Critical exponents for a dimer–dimer irreversible surface reaction

A dimer–dimer reaction model of the type A2+B2→2AB is investigated by means of computer simulations. The desorption of B2 dimer with probability P is studied. Here we investigate the critical behaviour. The critical exponents of our model do not fall into the Reggeon field theory or directed percolation universality class. The universality class of the reaction changes with changes in P.
