The total and topological 4Hep cross sections as well as the cross sections of the separate 4Hep interaction channels and the differential cross sections of the elastic 4Hep scattering were measured using the 2m hydrogen bubble chamber exposed to a separated beam of alpha-particles from the ITEP synchrotron at 5 GeV/c (the kinetic energy of the initial protons in the nuclear rest frame was 620 MeV). The data obtained have been compared with the results of the previous experiments and with the theoretical predictions based on the Glauber-Sitenko multiple-scattering theory.

The Quasielastic charge exchange reaction p He-3 ---> n(F) p p p at intermediate-energies

The basic characteristics of the quasi-elastic charge exchange reaction p 3 He→ n F ppp are investigated using the 80 cm ITEP liquid-hydrogen bubble chamber, which is exposed to beams of 3 He 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, T p = 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.

Cross-sections of He-4 interaction with protons and He-4 p elastic scattering at 2.7-GeV/c

The 2m hydrogen bubble chamber was exposed to a separated beam of α-particles from the ITEP synchrotron. The momentum of the 4 He-nuclei beam averaged over the bubble-chamber fiducial volume was equal to 2.7 GeV/ c (the kinetic energy of the initial protons in the nuclear rest frame was T p = 220 MeV). The total and topological cross sections were measured as well as the cross section of separate 4 He-p interaction channels and the differential cross sections d σ d t of the elastic 4 He-p scattering. The experimental results have been compared with the data of the previous experiments and with the theoretical predictions based on the Glauber-Sitenko multiple-scattering theory.

INVESTIGATION OF THE CHARGE EXCHANGE REACTION H-3 p ---> He-3 n AT 2.5-GeV/c TRITON MOMENTUM

Blinov, A.V. ; Chuvilo, I.V. ; Ergakov, V.A. ; et al.

J.Phys.G 8 (1982) 223, 1982.

Inspire Record 154213 DOI 10.17182/hepdata.40232

The differential cross sections d sigma /dt of the reactions 3H+p to 3He+n and 3H+p to 3H+p at a triton momentum of 2.5 GeV/c (equivalent to a proton kinetic energy Tp=318 MeV) have been measured. The ITEP 80 cm hydrogen bubble chamber was exposed to a 2.5 GeV/c separated triton beam. 2350 events of the reaction 3H(p,n)3He and 2574 events of the reaction 3H(p,p)3H were selected and analysed. Calculations performed in the framework of the multiple scattering theory taking the spin-isospin structure of the NN amplitude into account fit the data very well and show the high sensitivity of the charge-exchange cross section to the double spin-flip NN amplitudes.

INVESTIGATION ON THE REACTION t p ---> p d n AT 2.5-GeV/c TRITON MOMENTUM

The reaction of tp → pdn in 4π geometry was investigated by exposition of an 80 cm liquid hydrogen bubble chamber to a t-nucleus beam of 2.5 GeV/ c momentum. The main characteristics of the reaction are described reasonably well by the pole approximation in the absolute normalization and without free parameters.
