The dependence of the reaction cross section for all the alkali-methyl iodide reactions on the translationa! ener\_q in the range ET = O-40 kcal/mole has been discussed in an idealized collision model of hard-sphere interaction between couiding particles. In aI reactions of the family, the cross sec

β¦ Synopsis
The trends in the translational enera dependence of the reaction cross section and of the product energy distribution for the series of ,M f R1 reactions are discussed. The method is based on an assumed (model) dynamic constraint and the use of information theory to determine the reaction probability matrix which corresponds to the constraint. For different mass combinations, the energy dependence of the reaction cross section will exhibit a post-threshold maximum or minimum.
