Nuclear bremsstrahlung near the one‐ and two‐pion thresholds

The experiment on pp‐bremsstrahlung presented here aims at a detailed study of off‐shell effects in the strong interaction. A detector set‐up will be developed which allows measurements at maximum kinematically allowed photon energies, where the strongest deviations from the soft‐photon approximation (which incorporates only on‐shell information) are to be expected. The detector mainly consists of a large time‐of‐flight spectrometer covering the full solid angle.
