In the present work, we investigate the deuteron refraction effect in the exclusive () reactions. The refraction effect on the elementary process is taken into account by the local semiclassical approximation to the distorted waves. The results are compared with those obtained with the asymptotic momentum approximation, which is standardly applied to the distorted wave impulse approximation framework. It is shown that the refraction effect drastically changes the energy sharing distribution of the O()N reaction at 101.3 MeV and gives a better agreement with experimental data.
