Chaotic scattering in a molecular system

We examine the classical scattering dynamics of a chlorine atom interacting with an HO molecule using a two-dimensional model in which the HO bond length is held fixed. The classical phase space for this system is dominated by an unusually complicated homoclinic tangle. I will show how the fractal structure of the homoclinic tangle is encoded in all scattering functions and how this fractal structure can be easily investigated by defining a ``step number'' for each scattering trajectory.
