Neutron form-factors from quasielastic e d scattering

Bartel, W. ; Buesser, F.W. ; Dix, W.R. ; et al.
Phys.Lett.B 30 (1969) 285-288, 1969.
Inspire Record 56662 DOI 10.17182/hepdata.45282

The reaction e+d→e′+n+p was studied at electron scattering angles θ ⩽ 35° for four-momentum transfers of 0.39, 0.565 and 0.78 (GeV/ c ) 2 . By recording electron-neutron and electron-proton coincidences, the ratio of the electron scattering cross sections on quasi-free neutrons and protons was determined. An estimate of the binding effects, based on a Chew-Low-extrapolation, was made. Values for the neutron form factors were derived.

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

Bartel, W. ; Dudelzak, B. ; Krehbiel, H. ; et al.
Phys.Lett.B 28 (1968) 148-151, 1968.
Inspire Record 52791 DOI 10.17182/hepdata.45279

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.

Reaction K- p --> Lambda eta from 1.2 to 1.7 GeV/c

Flatte, Stanley M. ; Wohl, Charles G. ;
Phys.Rev. 163 (1967) 1441-1446, 1967.
Inspire Record 52559 DOI 10.17182/hepdata.26566

Total and differential cross sections of the reaction K−p→Λη have been determined for incident K− lab momenta between 1.2 and 1.7 BeVc. No striking resonance formation in the direct channel is seen; in particular, the Y0*(2100) decays not more than 3% via the Λη channel. A prominent forward peak in the differential cross sections indicates some crossed-channel meson-exchange activity. The branching ratio Γ(η→neutrals)Γ(η→π+π−π0) is 3.6±0.6.

We have analyzed 2560 events in the final-state K O 1 K O 1 n produced in π − p interactions at 5, 7 and 12 GeV/ c . We observe the S ∗ (1070), f O and A 2 decaying into K O 1 K O 1 . Resonance parameters, cross sections, and branching ratios are given.

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.
