Measurements of the Total $\pi$ He and $p$ He Cross-sections and the Slopes of the Forward Diffraction Peak at Energies From 50-{GeV} to 300-{GeV}

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.
Nucl.Phys.B 187 (1981) 205, 1981.
Inspire Record 154079 DOI 10.17182/hepdata.34264

Differential cross sections for elastic scattering of pions and protons on helium have been measured at incident momenta ranging from 50 to 300 GeV/ c in the t -range 0.008 < | < | < 0.05 (GeV/ c ) 2 . Both recoil α-particles and forward particles were detected in this experiment. The experimental method provided an absolute normalization of the cross sections with an estimated precision of 1%. From the analysis of the data, the diffraction slope parameters and total cross sections have been obtained. The results are compared with Glauber model calculations.

Sharp Backward Peak in p He-4 Elastic Scattering at 1.05-GeV

Berger, J. ; Duflo, J. ; Goldzahl, L. ; et al.
Phys.Rev.Lett. 41 (1978) 152-155, 1978.
Inspire Record 135350 DOI 10.17182/hepdata.20833

p-He4 elastic scattering has been measured at 1.05-GeV incident proton energy, close to 180° in the center of mass. The steep backward peak observed at lower energies is still present, but its slope appears to decrease.

Experimental Results on Elastic Scattering of Protons on the Light Nuclei H-2, H-3, He-3 and He-4 at 600-MeV

Fain, J. ; Gardes, J. ; Lefort, A. ; et al.
Nucl.Phys.A 262 (1976) 413-432, 1976.
Inspire Record 114032 DOI 10.17182/hepdata.37107

Differential cross sections for the elastic scattering of protons on 2 H, 3 H, 3 He and 4 He have been measured at 600 MeV. Proton-deuterium elastic scattering is investigated in a four-momentum transfer square t -range corresponding to Coulomb-nuclear interference in order to determine the nucleon-nucleon amplitudes at 600 MeV. For the other nuclei, we investigate the t -range corresponding to the first and second maximum, in order to determine the mechanism of the nuclear process. A few physical comments on the results are made.

Polarization and Differential Cross Sections in Proton-Proton and Proton-Nucleus Scatterings at 725 MeV

McManigal, Paul G. ; Eandi, Richard D. ; Kaplan, Selig N. ; et al.
Phys.Rev. 137 (1965) B620-B629, 1965.
Inspire Record 49431 DOI 10.17182/hepdata.26687

The polarization and angular distribution of protons scattered from protons, helium, beryllium, carbon, aluminum, calcium, iron, and tantalum were measured as functions of angle at 725 MeV. A variation of the usual double-elastic-scattering method was used, in that the sense of the first scattering angle was reversed in finding asymmetries, rather than the second angle. Energy analysis of the scattered beam was accomplished by means of a 102-degree magnetic spectrometer allowing a total resolution of ±10 MeV. The data were fitted with an optical model. In the proton-nucleus scattering the polarization reaches a maximum value of about 40% at angles less than the diffraction minimum. Results in proton-proton scatterings are more interesting; however, because of an uncertainty in the analyzing power of carbon, a definite statement cannot be made. One can say, however, that either the polarization in proton-proton scatterings is above 50% at this energy or the analyzing power of carbon at 6 deg and 600 MeV is more than 40%, which is considerably greater than the 30% measured at 725 MeV.
