  The interference of Deeply Virtual Compton Scattering (DVCS) and
Bremsstrahlung leads to a beam-charge asymmetry that can be observed for
exclusive photon production in the collision of high energy leptons and
nucleons/nuclei. Recent results for a hydrogen and a deuterium target are
reported and a consistent tendency for a rise of the cosine phi coefficient
with momentum transfer |t| has been found.
