STUDY OF THE MECHANISM OF THE He-3 p ---> p p d REACTION AT He-3 MOMENTUM OF 5-GeV/c

Blinov, A.V. ; Chuvilo, I.V. ; Drobot, V.V. ; et al.
Nucl.Phys.A 451 (1986) 701-727, 1986.
Inspire Record 214108 DOI 10.17182/hepdata.17644

The mechanism of the reaction 3 He + p → p + p + d is studied by making use of the ITEP 80 cm liquid-hydrogen bubble chamber exposed to a beam of 5 GeV/ c 3 He nuclei. The reaction cross section is equal to 20.6 ± 0.3 mb. The phase-space regions associated with quasifree scattering (QFS) and final-state interactions (FSI) are selected. Angular, mass and momentum distributions of the reaction products are obtained in the entire kinematically allowed range. The experimental data in the QFS region are compared with theoretical calculations based on the simplest pole-diagram approximation. The 3 He and deuteron wave functions (WF) correspond to the realistic RSC potential. The D-wave components of these WF are taken into account. The absolute value of the cross section and shape of the distributions are described as a whole reasonably well within the frame of the model considered in the kinematical region where FSI may be neglected. But at large spectator momenta there is an essential disagreement. The possible reasons for this are discussed.

Multiplicities of secondaries in interactions of 1.8-GeV/nucleon Fe-56 nuclei with photoemulsion and the cascade evaporation model

Dudkin, V.E. ; Kovalev, E.E. ; Nefedov, N.A. ; et al.
Nucl.Phys.A 509 (1990) 783-799, 1990.
Inspire Record 302290 DOI 10.17182/hepdata.36888

A nuclear photographic emulsion method was used to study the charge-state, ionization, and angular characteristics of secondaries produced in inelastic interactions of 56 Fe nuclei at 1.8 GeV/nucleon with H, CNO, and AgBr nuclei. The data obtained are compared with the results of calculations made in terms of the Dubna version of the cascade evaporation model (DCM). The DCM has been shown to satisfactorily describe most of the interaction characteristics for two nuclei in the studied reactions. At the same time, quantitative differences are observed in some cases.

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

Blinov, A.V. ; Vanyushin, I.A. ; Grechko, V.E. ; et al.
Nucl.Phys.A 510 (1990) 803-816, 1990.
Inspire Record 302181 DOI 10.17182/hepdata.36860

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.

THE H-3 + P ---> P + N + D REACTION AT A TRITIUM MOMENTUM OF 5-GEV/C

Abdullin, S.K. ; Blinov, A.V. ; Vanyushin, I.A. ; et al.
Nucl.Phys.A 506 (1990) 471-481, 1990.
Inspire Record 297384 DOI 10.17182/hepdata.15700

Using a liquid hydrogen bubble chamber of the ITEP, 80 cm in diameter, a study was made of the 3 H + p → p + n + d reaction with an incident momentum of 5 GeV/c for the tritium nuclei. The reaction cross section was 20.4 ± 0.2 mb. The angular, momentum and mass distributions of the reaction products in the 4π geometry have been obtained. We have separated the phase-space regions corresponding to quasi-free pn scattering and to the final-state Nd interaction. In the region of quasi-free pn scattering various experimental spectra are compared with the theoretical predictions, by using pole diagrams with nuclear vertex functions for three NN potentials: the Yamaguchi potential, the RSC potential and the potential in the quark-compound bag model. In the mass spectra of pn, pd and nd systems no evidence for the exhibition of two- and three-baryon resonances has been obtained.

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

Abdullin, S.K. ; Blinov, A.V. ; Chadeeva, M.V. ; et al.
Phys.Atom.Nucl. 56 (1993) 536-539, 1993.
Inspire Record 344565 DOI 10.17182/hepdata.40023

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.
