Electrodisintegration of the Deuteron Around q2=3.5 F-2

Grossetete, B. ; Jullian, S. ; Lehmann, P. ;
Phys.Rev. 141 (1966) 1435-1440, 1966.
Inspire Record 944958 DOI 10.17182/hepdata.462

We have measured the absolute cross sections of the electron-deuteron scattering at q2=3.5 F−2 and obtained the complete inelastic spectrum. Three points for each spectrum are given with a 4% accuracy. The scattering angles, 60° and 130°, were chosen to allow the separation between electric and magnetic scattering. Calculations of radiative corrections were made in order to permit the comparison of the spectra with the inelastic-scattering theories.

Measurement of Proton Electromagnetic Form Factors at High Momentum Transfers

Chen, K.W. ; Dunning, J.R. ; Cone, A.A. ; et al.
Phys.Rev. 141 (1966) 1267-1285, 1966.
Inspire Record 50783 DOI 10.17182/hepdata.26655

Elastic electron-proton scattering cross sections have been measured using the internal beam of the 6-BeV Cambridge Electron Accelerator at laboratory scattering angles between 31° and 90° for values of the four-momentum transfer squared ranging from q2=0.389 to 6.81 (BeV/c)2 (q2=10 to 175F−2). Incident electron energies ranged from 1.0 to 6.0 BeV. Scattered electrons from an internal liquid-hydrogen target were momentum-analyzed using a single quadrupole spectrometer capable of momentum analysis up to 3.0 BeV/c. Čerenkov and shower counters were used to help reject pion and low-energy background. The cross sections presented are absolute cross sections with experimental errors ranging from 6.8% to 20%. Separation of proton electromagnetic form factors have been made for all but the two highest momentum transfer points, using the Rosenbluth formula. Both form factors, GEp and GMp, were observed to continue to decrease as the momentum transfer increases. An upper limit to the possible asymptotic values of the proton electromagnetic form factors has been established.

Elastic Electron-Deuteron Scattering

Grossetete, B. ; Drickey, D. ; Lehmann, P. ;
Phys.Rev. 141 (1966) 1425-1434, 1966.
Inspire Record 944959 DOI 10.17182/hepdata.26656

We present results on elastic electron-deuteron experiments performed at Orsay. The range of momentum transfers is 0.6 to 2 F−2. Two kinds of measurements have been taken detecting the scattered electron: one with a solid CD2 target, the other with a liquid target. The data are analyzed with the nonrelativistic theory, which gives slightly positive neutron form factors and a magnetic neutron form factor nearly equal to the magnetic proton form factor.

eta Production near Threshold

Phys.Lett. 23 (1966) 597, 1966.
Inspire Record 50962 DOI 10.17182/hepdata.29781

A study of π − + p →η + n near threshold shows that the cross section rises linearly with η momentum and that Λ η < 0.9 MeV c 2 (95% confidence limit).

Proton form factors from elastic electron-proton scattering

Janssens, T. ; Hofstadter, R. ; Hughes, E.B. ; et al.
Phys.Rev. 142 (1966) 922-931, 1966.
Inspire Record 49127 DOI 10.17182/hepdata.26698

Absolute measurements of the elastic electron-proton cross section have been made with a precision of about 4% for values of the square of the four-momentum transfer, q2, in the range 6.0 to 30.0 F−2 and for electron scattering angles in the range 45° to 145°. To within the experimental errors, it is found that the charge and magnetic form factors of the proton have a common dependence on q2 when normalized to unity at q2=0, and that an accurate representation of the behavior of the form factor and that of the cross sections themselves can be given in terms of a three-pole approximation to the dispersion theory of nucleon form factors.
