Continuous slowing down theory calculations have been found to yield significant discrepancies in the presence of strong absorption. An algorithm has been formulated for evaluating continuous slowing down theory parameters that should be applicable for cases with strong absorption. Excellent agreement with more precise calculations is obtained when the new parameters are used.
