PION PRODUCTION IN np COLLISIONS AT 1.25 GeV WITH HADES

Preliminary results on charged pion production in np collisions at an incident beam energy of 1.25 GeV obtained with HADES are presented. The np reactions were studied in dp collisions at 1.25 GeV/u using a Forward Wall hodoscope, aimed at registering spectator protons. The separation of np → ppπ^-, np → npπ⁺π^- and np → dπ⁺π^- channels is demonstrated.
