Abstract

The results of double pion production in np and pp collisions at an incident beam energy of 1.25 GeV with the HADES spectrometer at GSI are presented. The np-reactions were studied in d p collisions at 1.25 GeV/u using Forward Wall hodoscope aimed at registering spectator protons. High statistic invariantmass and angular distributions are obtained within the HADES acceptance which are compared with phase-space distributions.
