Measurement of sigma(tot) in proton proton scattering in pure spin states

Parker, E.F. ; Ratner, L.G. ; Brown, B.C. ; et al.
Phys.Rev.Lett. 31 (1973) 783-786, 1973.
Inspire Record 83779 DOI 10.17182/hepdata.21350

An experiment was done using the new accelerated polarized proton beam at the Argonne National Laboratory zero-gradient synchrotron and a polarized proton target. The total cross section for proton-proton scattering at 3.5 GeV/c was measured in the spin states ↑↑ and ↑↓ perpendicular to the beam direction. The two cross sections were found to be equal within the experimental error of ±5%.

Production of charged pions by 730-MeV protons from hydrogen and selected nuclei

Cochran, D.R.F. ; Dean, P.N. ; Gram, P.A.M. ; et al.
Phys.Rev.D 6 (1972) 3085-3116, 1972.
Inspire Record 73637 DOI 10.17182/hepdata.22253

An experiment was done in the external proton beam of the Berkeley 184-in. cyclotron to measure the production cross sections for pions from various target nuclei, from hydrogen to lead. The cross-section data are presented and the reaction mechanisms discussed. The hydrogen production appears to fit the one-pion-exchange model.

Proton Compton Effect for 300-MeV Photons

Gray, E.R. ; Hanson, A.O. ;
Phys.Rev. 160 (1967) 1212-1215, 1967.
Inspire Record 944949 DOI 10.17182/hepdata.26568

The scattering of photons by protons has been measured with a spark-chamber technique using 335-MeV bremsstrahlung. The experimental values obtained at 90° and 135° are compared with those calculated by Contogouris using dispersion relations. The agreement is reasonable except for a persistently low point for 310 MeV at 90°.
