Abstract
A study of\(\bar np\) annihilations with\(\bar n\) momentum between 0.5 and 0.8 GeV/c is presented. The search fors-channel resonances in\(\bar np\) annihilations reveal possibly two narrow structures in the odd pions final state. Inclusiveρ 0 andf 0 cross sections in\(\bar np\) annihilations have been estimated to be 9.0±0.6 mb and 3.4±0.6 mb respectively. Longitudinal and transverse momentum distributions for inclusiveρ 0 production have been presented. A study of resonance production in exclusive final state revealsρ 0 production to be dominant in the odd pion final states andρ +,ω 0 productions are most important for the even pion final states. Theπ + π − effective mass spectra in the backward and the forward directions in the\(\bar np\) c.m. system have been examined for a possible ϱ-ω interference effect.
