Popis: Results on np annihilation frequencies into π + π 0 , π + η and K + K s final states in the n momentum range between 50 and 400 MeV/c are presented. Information about np annihilation dynamics at low energy have been extracted as well as the first determination of the D-wave contribution to the annihilation in flight below 400 MeV/c . This result is compared with an independent analysis of the np annihilation cross section data.
