To calculate the integrals defining the source term and the flux term, appropriate expressions for Aip and ip[ — ipi have to be determined from an analysis of the inelastic binary particle collision dynamics. 

In this section, particle particle collision dynamics will be discussed. A hard sphere approach is used for the particle particle collision analysis. In this approach, it is assumed that collisions between spherical particles are binary and quasi-instantaneous, and further, that there is a sequence of collisions during each time step. The equations, which are similar to the stepwise molecular dynamic simulation, are used to locate the minimum flight time of particles before any collision. 

With the advent of the molecular beam technique it became possible to get valuable information on two-particle collision dynamics. Studies on the angular distribution of products and determination of their internal state at a fixed, sufficiently narrow initial distribution of reagents over velocities and rotational and vibrational states enable evaluation of the reaction cross sections.
