We propose to extend the optimal Fermi averaging procedure theoretically in order to calculate an in-mediumamplitude for the exothermic () reaction on nuclei in the framework of a distorted-wave impulse approximation, taking into account the local momentum transfer generated by semiclassical distorted waves forandmesons. Angular distributions for thereaction in which a momentum transfer isMeV/atMeV/in theforward direction are estimated by applying the extended procedure. The result shows that the calculated angular distributions are in good agreement with those of the data, and this extension is a successful prescription making it possible to describe the reaction cross sections in near-recoilless reactions such as () in our framework.
