The methods of Prigogine and Resibois are used to construct a description of classical twohyphen;body scattering events which bears a close formal analogy to that of timehyphen;dependent quantumhyphen;scattering theory. It is shown how the distribution in phase space evolves after long times into a steadyhyphen;state scattering form, from which expressions for cross sections and transition rates are obtained by means similar to those of the quantumhyphen;mechanical treatment. These expressions are shown to be equivalent to the conventional classical formulas but offer in principle alternative means of evaluation.
