Abstract: Motivated by realistic scattering processes of composite systems, we study the dynamics of a two-particle bound system which is scattered at a mirror. We consider two different scenarios: In the first case we assume that only one particle interacts directly with the mirror whereas in the second case both particles are scattered. The coherence between the transmitted and the reflected wave packet is reduced when the internal degree of freedom (the relative coordinate) of the bound system becomes excited. Depending on the particular system-mirror interaction, long-lived resonances can occur.
