Abstract
The preliminary results on charged pion production in np collisions at an incident beam energy of 1.25 GeV measured with HADES are presented. The np reactions were isolated in dp collisions at 1.25 GeV/u using the Forward Wall hodoscope, which allowed to register spectator protons. The results for np -> pppi-, np -> nppi_s16pi- and np -> dpi_s16pi- channels are compared with OPE calculations. A reasonable agreement between experimental results and the predictions of the OPE_s16OBE model is observed.
