Adsorption of anisometric particles (discorectangles) on a two-dimensional substrate has been studied. The aspect ratio (the length-to-width ratio ɛ = l/d) was changed within the interval ɛ = 1–10. A modified random sequential adsorption (RSA) model is studied. In this model, the particles were covered with repulsive shells. The main parameters of the model are the thickness Rc of the permeable shell and the maximum number Zm of the shells of the nearest particles that can be crossed by the shell of the next deposited particle. The behavior of the degree of surface coverage in the saturated (jammed) state at various values of the parameters Rc, Zm, and ɛ is discussed.
