Quasielastic Electron-Deuteron Scattering Between q$^2$=18f$^{-2}$ and 100f$^{-2}$

Albrecht, W. ; Behrend, H.J. ; Dorner, H. ; et al.

Phys.Lett.B 26 (1968) 642-644, 1968.

Inspire Record 53149 DOI 10.17182/hepdata.29312

Quasielastic e-d scattering measurements were performed up to q 2 = 100 fm −2 . Only the electron was detected. The ratio R= ( d 2 ω d Ω d E′) ed d ω d Ω) ep was measured at the quasielastic peak; the magnetic form factor G M N of the neutron was deduced using the assumption G E N = 0.

Electroproduction of pions near the $\Delta(1236)$ isobar and the form-factor $G^*_M(q^2)$ of the $({\gamma} N\Delta)$ vertex

Phys.Lett.B 28 (1968) 148-151, 1968.

The cross section for inelastic electron-proton scattering was measured at incident electron energies of 1.5 to 6 GeV by magnetic analysis of the scattered electrons at angles between 10° and 35°. For invariant masses of the hardonic final state W ⩽ 1.4 GeV. the measured spectra are compared with theoretical predictions for electroproduction of the Δ(1236) isobar. The magnetic dipole transition form factor G ∗ M ( q 2 ) of the (γ N Δ)-vertex is derived for momentum transfers q 2 = 0.2 − 2.34 (GeV/ c ) 2 ard found to decrease more rapidly with q 2 than the proton form factors.

Electromagnetic form-factors of the proton between 5 and 50 1/fm-squared

Berger, Christoph ; Gersing, E. ; Knop, G. ; et al.

The external beam of the 2.5 GeV-electron-synchrotron has been used to measre elastic electron proton scattering at four-momentum-transfers between 15 and 50 fm −2 . By combining these results with measurements at small angles at DESY, we have obtained the electric and magnetic form factors separately. Their ratio shows a deviation from the scaling law.

Inspire Record 56843 DOI 10.17182/hepdata.29077

Inelastic electron proton scattering has been measured by detecting the scattered electron, thus obtaining the total absorption cross section for virtual photons. Two complete spectra from threshold to a pion nucleon mass of W = 2 GeV were taken at θ e = 48.3° and fixed primary energies of 3.963 GeV and 5.159 GeV, respectively, corresponding to a momentum transfer at the first resonance of q 2 = 3.98 (GeV/ c ) 2 and q 2 = 5.84 (GeV/ c ) 2 . In addition, a measurement at θ e = 47.9° and at a primary energy of 3.306 GeV in the region of the first resonance is reported.

MUON PROTON INELASTIC SCATTERING q2 LESS THAN 1.2-GeV/c-2

Dieterle, B. ; Braunstein, T. ; Cox, Jack ; et al.

Phys.Rev.Lett. 23 (1969) 1187-1190, 1969.

Inspire Record 54876 DOI 10.17182/hepdata.21667

The inelastic scattering of muons has been measured using positive muons of momentum 10 GeV/c incident upon a liquid-hydrogen target. We present values of the differential cross section and of the virtual photon-photon absorption cross section for |q| in the range 0.05 to 1.2 (GeV/c)2 and for equivalent photon laboratory energies of 0.6 to 6.5 GeV.

High-Energy Inelastic e p Scattering at 6-Degrees and 10-Degrees

Bloom, Elliott D. ; Coward, D.H. ; DeStaebler, H.C. ; et al.

Phys.Rev.Lett. 23 (1969) 930-934, 1969.

Inspire Record 54874 DOI 10.17182/hepdata.21635

Cross sections for inelastic scattering of electrons from hydrogen were measured for incident energies from 7 to 17 GeV at scattering angles of 6° to 10° covering a range of squared four-momentum transfers up to 7.4 (GeV/c)2. For low center-of-mass energies of the final hadronic system the cross section shows prominent resonances at low momentum transfer and diminishes markedly at higher momentum transfer. For high excitations the cross section shows only a weak momentum-transfer dependence.

Dependence of nu nucleus cross-sections on the mass number

Borer, K. ; Hahn, B. ; Hofer, H. ; et al.

Phys.Lett.B 30 (1969) 572-575, 1969.

Inspire Record 63243 DOI 10.17182/hepdata.50061

High energy v -nucleus cross sections have been compared for Pb, Fe, Al and C as target nuclei, exposed to the CERN v -beam. The events with θ vμ < 29 0 and p μ ⪆ 1 GeV /c have rates in the ratio of the mass number of the nuclei. Also a restricted sample with q 2 ⪅ 0.1 (GeV/ c ) 2 and θ vμ < 5 0 does not reveal a theoretically predicted deviation from A -proportionality, although due to the limited statistical accuracy in this restricted sample an “ A 2 3 - contribution ” of several tenths cannot be excluded either.
