摘要：

In this work we study, by means of the Monte Carlo technique, the adsorption kinetics of ''hot'' dimers, i.e., molecules which after adsorption dissociate and each of the remaining monomers fly apart up to a maximum distance R from the original adsorption site. We have evaluated the jamming coverage (theta(j)) which depends on R and differs from the standard random dimer filling problem. Also the dependence of both the sticking coefficient and the average distance traveled by the monomers on theta is studied and discussed. ''Hot'' monomers exhibit an enhanced probability for encounters with other adparticles. This behavior may be relevant in the dynamic of some catalytic processes.
