The angular distributions of K⁺p and π⁺p backward elastic scattering have been measured at 5.2 and 6.9 GeV/c. Backward π^-p and K^-p elastic scattering were studied at 6.9 GeV/c. Backward peaks are observed in K⁺p scattering with an energy dependence of the form s⁻⁴.

We present results of measurements of the differential cross sections for the following elastic-scattering reactions: (i) π + p at 5.2 and 7.0 GeV/ c in the range −1 < u < 0.02 (GeV/ c ) 2 , (ii) π − p at 7.0 GeV/ c in the range −0.7 < u < 0.05 (GeV/ c ) 2 , (iii) K + p at 5.2 and 7.0 GeV/ c in the ranges −1 < t < −0.01 (GeV/ c ) 2 and −1 < u < 0 (GeV/ c ) 2 , and K − p at 7.0 GeV/ c in the range −1 < u < 0 (GeV/ c ) 2 .

Measurements of anti-deuteron absorption and stripping cross sections at the momentum 13.3 gev/c

Denisov, S.P. ; Donskov, S.V. ; Gorin, Yu.P. ; et al.

Nucl.Phys.B 31 (1971) 253-260, 1971.

Inspire Record 68562 DOI 10.17182/hepdata.33323

The absorption cross sections of antideuterons with the momentum P = 13.3 GeV/ c by Li, C, Al, Cu and Pb nuclei have been measured. Antiproton stripping of antideuterons has been registered and its cross section for C, Al and Cu has been defined. The binding energy of antideuteron is found to be ε d = 2.4 ± 0.6 MeV by measuring the angular distribution of antiprotons from stripping.

Backward rho+ production in pi+ p reactions at 5.2 gev/c

Carlson, P.J. ; Fleury, P. ; Lundby, A. ; et al.

Phys.Lett.B 33 (1970) 502-504, 1970.

Inspire Record 69380 DOI 10.17182/hepdata.28538

Using wire spark chambers we have observed the backward production of ϱ + mesons in the reaction π + p → p (missing mass) at 5.2 GeV/ c . In the four-momentum interval −0.80 < u < −0.006 (GeV/ c ) 2 the angular distribution shows a backward peak. In contrast to backward π + p elastic scattering, there is no dip in the angular distribution at u ≈ −0.15 (GeV/ c ) 2 . The ϱ + decay is found to be compatible with isotropy.

3 H̃e nuclei were observed in the negative beam, produced by 70 GeV protons on an Al target. Five 3 H̃e have been identified among 2.4 · 10 11 particles that passed through the apparatus. Scintillation and Čerenkov counters were used to measure the electrical charge and velocity of particles. The mass of 3 H̃e is found to be M 3 H ̃ e = (1.00 ± 0.03)3m p , the charge is z = (0.99 ± 0.03)2 e . The ratio of differential production cross sections of 3 H ̃ e (P = 20 GeV /c) and π − (P = 10 GeV/c ) equals 2 · 10 −11 . This corresponds to antihelium −3 production cross section d 2 σ 3 H ̃ e / d Ω d P = 2.0 · 10 −35 cm 2 / sr · GeV /c per Al nuclei and 2.2 · 10 −36 cm 2 sr · GeV/ c per nucleon.
