Abstract
Dilepton production has been measured with HADES, the _s15High Acceptance DiElectron Spectrometer_s15. In pp collisions at 2.2GeV kinetic beam energy, exclusive eta production and the Dalitz decay eta -> gamma e_s16e- has been reconstructed. The electromagnetic form factor is well in agreement with existing data. In addition, an inclusive e_s16e- spectrum from the C_s16C reaction at 2AGeV is presented and compared with a thermal model.
