Inspire Record 68563 DOI 10.17182/hepdata.41500

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.

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.

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.
Nucl.Phys.B 57 (1973) 77-99, 1973.
Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.

Differential cross sections for charge exchange π − p → π 0 n have been measured for momenta up to 50 GeV/ c . The cross section falls as a power of energy. The forward scattering cone shrinks with increasing energy. The cross section for charge exchange at zero angle drops with momentum as P −0.81±0.05 . The charge exchange cross section in the region of the second maximum decrease as P −2.8±0.1 . The ϱ trajectory is described by a linear function α ( t ) = 0.56 + 0.97 t in the interval 0 < − t -<1.5 (GeV/ c ) 2 .

Nucl.Phys.B 85 (1975) 158-164, 1975.
Inspire Record 90365 DOI 10.17182/hepdata.32132

The charge-exchange cross sections were measured for π − on Li, C, Al and Cu nuclei at momentum 48 GeV/ c . By comparing the data obtained for nuclei with those for hydrogen under the same conditions the effective numbers of protons are defined. The conclusion is made that η 0 mesons are absorbed in nuclei weaker then π 0 . The total cross section of η 0 interactions with the nucleon is determined to be σ tot ( η 0 N) = 15 ± 5 mb in agre ement with the quark model.
