Oscillatory conglomeration in methane and methane-chlorine films deposited at liquid helium temperatures

Oscillatory conglomeration in a methane-chlorine solid-phase mixture obtained by vapor condensation at liquid helium temperatures and in pure methane is observed in a full-scale experiment. The vapor-phase growth of a film under severe quenching conditions is described in detail. The oscillatory regime results from supersaturation with vacancies due to long-range aggregation in the lyophobic disperse system. An algorithm for a modified model of diffusion-limited aggregation is suggested. It provides reversible controllable drain-source switching for vacancies and is intended for computer simulation of conglomeration oscillations.
