    "abstract": "Using a multipole expansion of the radiated field generated by a classical\nelectric current, we present a way to interprete the bremsstrahlung spectra of\nlow energy heavy ion collisions. We perform the calculation explicitely for the\nsystem ^{12}C+ ^{12}C at 84AMeV and compare the result with the experimental\ndata of E. Grosse et al. Using simple model assumptions for the electromagnetic\nsource current we are able to describe the measured data in terms of coherent\nphoton emission. In this context, the information contained in the measured\ndata is discussed.",
