Results on (n) over bar p annihilation frequencies into pi(+) pi(0), pi(+)eta and K+KS final states in the (n) over bar momentum range between 50 and 400 MeV/c are presented. Information about <(n)over bar p> 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.

Abstract
Results on (n) over bar p annihilation frequencies into pi(+) pi(0), pi(+)eta and K+KS final states in the (n) over bar momentum range between 50 and 400 MeV/c are presented. Information about <(n)over bar p> 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 <(n)over bar p> annihilation cross section data.
