Analysis of the reaction sup 3 He p r arrow 2 p 2 n. pi. sup + at a sup 3 He momentum 5 GeV/ c in the complete phase space
- Institute of Theoretical and Experimental Physics, State Commission on Use of Atomic Energy (SU)
The 80-cm diameter liquid-hydrogen bubble chamber at our institute, exposed in a separated beam of {sup 3}He nuclei with momentum 5 GeV/{ital c}, has been used to study for the first time the reaction {sup 3}He{ital p}{r arrow}2{ital p}2{ital n}{pi}{sup +}. A total of 3509 events of this reaction were selected, which corresponds to a cross section 14.4{plus minus}0.2 mb. On the basis of the pole model with interaction of the spectator nucleons in the final state in the complete phase space a study has been made of the angular, mass, and momentum spectra. From analysis of the effective mass of the {ital p}{pi}{sup +} system it follows that the {Delta}{sup ++} isobar is formed in the reaction {sup 3}He{ital p}{r arrow}2{ital p}2{ital n}{pi}{sup +} in peripheral quasifree {ital pN} collisions without broadening. In the reaction studied on indications were obtained of the formation of two-baryon or three-baryon resonances.
