Ekstrand, K. ; Browman, A. ; Hand, L. ; et al.
Phys.Rev.D 6 (1972) 1-11, 1972.
Inspire Record 74041 DOI 10.17182/hepdata.3606

The reaction γ+p→π++n has been measured for incident γ-ray energies from 0.7 to 8 GeV and recoil lab angles from 170° to 180° using the Cornell 10-GeV synchrotron. The data presented here cover the transition region between the resonance region and the high-energy region studied at SLAC. The results are compared with various phenomenological Regge-pole analyses and with similar data on π0 photoproduction taken at DESY.

Wide-angle proton-proton elastic scattering from 1.3 to 3.0 gev/c

Williams, D.T. ; Bloodworth, I.J. ; Eisenhandler, E. ; et al.
Nuovo Cim.A 8 (1972) 447-469, 1972.
Inspire Record 78276 DOI 10.17182/hepdata.37468

Differential cross-sections for proton-proton elastic scattering have been measured covering the angular range from 50° to 90° c.m. at twelve incident momenta from 1.3 to 3.0 GeV/c. The angular distributions are quite smooth, but there is evidence of structure in the energy dependence of fixed-angle cross-sections at |t| ∼ 1 (GeV)2.

We present the results on total channel cross-sections obtained in the Saclay 180 l HBC exposed to a separated K− beam at Nimrod. The cross-sections for each channel are given at 13 incident K− momenta between 1.26 and 1.84 GeV/c.

We have measured the differential cross-section for the reaction p p → π + Λ − at 5 GeV /c , the π + being in t he cm angular range 0.47 < cos θ p π + cm < 0.98 , corresponding to 0.12 < − t < 2.40 (GeV/ c ) 2 . The angular distribution has a forward peak with a differential cross-section d σ d ω = 4.1 ± 1.6 μ b / sr for 0.94 < cos θ p π + cm < 0.96 .

Inspire Record 75806 DOI 10.17182/hepdata.28333

Proton-proton elastic scattering has been measured over the four-momentum transfer squared 0.0007 ⩽ t ⩽ 0.02 GeV 2 /c 2 . A gas hydrogen jet has been used as an internal target of the accelerator. The results indicate that the ratio of the real to the imaginary part of the proton-proton forward scattering amplitude rises smoothly with increasing energy from α = −0.35 ± 0.05 at p = 9.39 GeV/ c to α = −0.092 ± 0.011 at p = 69.8 GeV/ c .

Phys.Lett.B 38 (1972) 452-456, 1972.
Inspire Record 75815 DOI 10.17182/hepdata.28334

The measurements of the transmission regeneration amplitude on hydrogen in the momentum region of 14–42 GeV/ c indicate that in accordance with the Pomeranchuk theorem its magnitude |ƒ° − ƒ °|/k decreases as energy increases and its phase is approximately constant and equal to arg (ƒ° − ƒ °) = (−118 ± 13)° .
