Electron-Proton Scattering at High-Momentum Transfer

Berkelman, K. ; Feldman, M. ; Littauer, R.M. ; et al.
Phys.Rev. 130 (1963) 2061-2068, 1963.
Inspire Record 46839 DOI 10.17182/hepdata.26788

The elastic electron-proton scattering cross section has been measured at laboratory angles between 90° and 144° and for values of the four-momentum transfer squared between 25 and 45 F−2 (incident electron laboratory energies from 830 to 1360 MeV). Both the scattered electrons and the recoil protons were momentum analyzed and counted in coincidence, making possible background-free measurements down to cross sections of the order of 10−35 cm2/sr. The data are consistent with the Rosenbluth formula, and the resulting form factors tie on well with previous measurements at lower momentum transfer, continuing the established trend.

ELECTRON - PROTON SCATTERING AT LOW MOMENTUM ENERGIES

Lehmann, P. ; Taylor, R.E. ; Wilson, Richard ;
Phys.Rev. 126 (1962) 1183, 1962.
Inspire Record 16521 DOI 10.17182/hepdata.26811

We have measured the electron-proton scattering cross section at 248.9 Mev, 104.81°; 209.6 Mev, 149.75°; and 139.3 Mev, 104.19°. We find the following values: F1=0.767±0.025, F2=0.707±0.028, and F1F2=1.085±0.025 at −q2=2.98 f−2. F=0.902±0.011 at −q2=1.05 f−2. The last result agrees with previous measurements. The others are new contributions.

Study of the process $e^+⁢e^-\to \pi^+\pi^-\pi^0$ in the energy range 840-1020 MeV on the VEPP-2M storage ring with the Cryogenic Magnetic Detector

The CMD-2 collaboration Barkov, L.M. ; Vasserman, I.B. ; Vorobev, P.V. ; et al.
Budker Institute Preprints (1989) 15, 1989.
Inspire Record 2774417 DOI 10.17182/hepdata.151397

On the electron-positron storage ring VEPP-2M using the Cryogenic Magnetic Detector, the cross section of the e+e- -> π+π-⁢π0 process was measured in the energy range 2x420-2x510 MeV. The energy dependence of the cross section is consistent with the predictions of the vector dominance model taking into account the interference of omega and phi mesons. The optimal value of the omega-phi interference phase is 136+-36+-10 degree.
