Privman V. DISSOCIATIVE ADSORPTION: A SOLVABLE MODEL (14K, TeX (plain)) ABSTRACT. A model of "hot"-dimer deposition in one dimension, introduced by Pereyra and Albano, is modified to have an unbounded dissociation range. The resulting dynamical equations are solved exactly. A related k-mer dissociation model is also introduced and its solution obtained as a quadrature.
