Shabalin, E. P.

This paper focuses on an optional model of radical recombination in solid methane, apart from conventional theory. It shares the common property of two-order reactions, but accounts for local nonuniformitites of the objects involved (such as radical concentration, the track nature of energy deposition, and others). Accounting for local nonuniformity provides absolutely different results for the time dependence of the space-averaged concentration of radicals, both for the processes of their storage and 'burping', compared to the common approach; it also brings new conditions for the thermal instability of the methane slug under irradiation and gives a better understanding of most of the strange features of burp performances.
