Description
The production of ρ+, N33*, and η0 was observed in π+p interactions at 1.6 GeV/c. In the reactions where one pion is created, the comparison between the experimental distribution of the ρ+ and the N33* with the predictions of the peripheral model modified by absorption effects permits the conclusion that the contribution of this model is important, but that other effects such as interferences between ρ+ and N33* are not negligible. In the reactions where several pions are created, the branching ratios of some decay modes of η0 are evaluated and the associated production of η0 and N33* is observed. (author)

La production des resonances ρ+, N33* et η0 a ete observee dans les interactions π+p a 1,6 GeV/c. Dans les reactions ou un seul meson π est cree, la comparaison des distributions experimentales relatives au meson ρ+ et a l'isobare N33* aux previsions du modele peripherique modifie par les effets d'absorption, permet d'affirmer que la contribution de ce modele est importante, mais que des effets tels que les interferences entre les processus de creation du ρ+ et de N33* ne sont pas negligeables. Dans les reactions ou plusieurs mesons π sont crees, les rapports de branchement de certains modes de desintegration du meson η0 ont pu etre evalues et la production associee du η0 et de N33* a ete observee.
