Collision cascade, microscopic

Thus as a starting point for understanding the bombardment process we have developed a classical dynamics procedure to model the motion of atomic nuclei. The predictions of the classical model for the observables can be compared to the data from sputtering, spectrometry (SIMS), fast atom bombardment mass spectrometry (FABMS), and plasma desorption mass spectrometry (PDMS) experiments. In the circumstances where there is favorable agreement between the results from the classical model and experimental data It can be concluded that collision cascades are Important. The classical model then can be used to look at the microscopic processes which are not accessible from experiments In order to give us further insight into the ejection mechanisms. 

In order to elucidate the dynamical features of a hot atom reaction, the microscopic time dependent collision cascade must be modeled. Provided that the required reactive and nonreactive cross section data are available, this can be accomplished using the steady state hot atom kinetic theory ( ). This section contains a brief introduction to.the mathematical apparatus.
