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.

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.
