摘要：

The basic characteristics of the quasi-elastic charge exchange reaction p3He→ nFppp are investigated using the 80 cm ITEP liquid-hydrogen bubble chamber, which is exposed to beams of 3He nuclei with momenta of 2.5 and 5 GeV/c (the kinetic energy of primary protons in the rest system of the nucleus are, respectively, Tp = 0.318 and 0.978 GeV). The experimental data are compared with the predictions of the Glauber-Sitenko multiple scattering theory and of the pole model, taking into account the interaction between spectator nucleons in the final state. In the mass spectrum of the 3p system at 3.05 GeV a clearly denned structure has been revealed, which is not described within the pole model. A possible resonance origin of the given structure is discussed. © 1990.
