Description

The High Acceptance Di-Electron Spectrometer HADES at GSI, Darmstadt, has been designed for systematic studies of hadron properties inside nuclear matter. First measured mass and momentum distributions of e+e- pairs produced in 12C+12C collisions at 1 and 2 AGeV are presented and compared with p+p collisions at 2.2 GeV incident energy. The spectrometer set-up and the analysis methods are briefly outlined and a comparison of the data with Monte-Carlo events from a generator based on known production cross-sections and branching ratios is shown and discussed.
