A brief description of the Surrogate reaction method, an indirect approach for determining compound-nuclear reaction cross sections, is presented. The Weisskopf-Ewing limit, an approximation scheme that is typically employed in the analysis of Surrogate experiments, is considered and its validity and limitations are discussed.
