Cross-sections of the interactions of He nuclei with protons

4He-p collisions at two values of4He momenta 8.6 GeV/c and 13.6 GeV/c as well as the3He-p collisions at 13.5 GeV/c have been studies using the one-meter JINR hydrogen bubble chamber. Total, elastic, topological and reaction cross sections have been measured. The cross sections have been determined on a sample of minimum biased events.

Measurements of Elastic Scattering in $\alpha^- \alpha$ and $\alpha$ - Proton Collisions at the {CERN} Intersecting Storage Rings

The CERN-Naples-Pisa-Stony Brook collaboration Ambrosio, M. ; Anzivino, G. ; Barbarino, G. ; et al.
Phys.Lett.B 113 (1982) 347-352, 1982.
Inspire Record 176959 DOI 10.17182/hepdata.30919

We measured the elastic scattering of αα at s = 126 GeV and of α p at s = 89 GeV . For αα , the differential cross section d σ /d t has a diffractive pattern minima at | t | = 0.10 and 0.38 GeV 2 . At small | t | = 0.05−0.07 GeV 2 , this cross section behaves like exp[(100 ± 10) t ]. Extrapolating a fit to the data to the optical point, we obtained for the total cross section α tot ( αα ) = 250 ± 50 mb and an integrated elastic cross section σ e1 ( αα ) = 45 ± mb. Another method of estimating σ tot ( αα ), based on measuring the interaction rate, yielded 295 ± 40 mb. For α p, d σ /d t has aminimum at | t | = 0.20 GeV 2 , and for 0.05 < | t | < 0.18 GeV 2 behaves like exp[(41 ± 2) t ]. Extrapolating this slope to | t | = 0, we found σ tot ( α p) = 130 ± 20 and σ e1 ( α p) = 20 ± 4mb. Results on pp elastic scattering at s = 63 GeV agree with previous ISR experiments.

Measurement of Medium-Energy alpha-Proton Elastic Scattering Beyond the First Minimum Region

Berger, J. ; Duflo, J. ; Goldzahl, L. ; et al.
Phys.Rev.Lett. 37 (1976) 1195-1198, 1976.
Inspire Record 116144 DOI 10.17182/hepdata.21086

The α-proton elastic scattering has been measured with α particles at equivalent incident proton energies of 438, 648, and 1036 MeV. A structure is observed at the position where a second minimum is expected in the differential cross section. Comparison with improved versions of the Glauber model are presented.

Alpha-Proton Elastic Scattering in the Backward Hemisphere

Phys.Lett.B 63 (1976) 111-114, 1976.
Inspire Record 101104 DOI 10.17182/hepdata.27659

Incident alphas on protons were used to measure the elastic cross section in the backward hemisphere at 3.20, 4.00, 5.08 and 6.00 GeV/ c . The level and shape of the angular distributions are strongly dependent on energy. A backward peak shows up at 4.00 GeV/ c and become much steeper when the energy increases.
