| Abstract: | We discuss the effect of the Fermi motion on the angular momentum states of anti-proton-nucleon annihilation at rest in deuterium. For annihilations from S-orbitals we find an important contribution of the P-wave in the system with a peculiar shape of the “spectator” momentum spectrum. A cut on the spectator momentum can therefore reduce this contribution to a very small level. |
