Coincidence electroproduction of single neutral pions in the resonance region at q 2 = 0.5 (GeV/ c ) 2

Latham, A. ; Allison, J. ; Booth, I. ; et al.
Nucl.Phys.B 156 (1979) 58-92, 1979.
Inspire Record 1392686 DOI 10.17182/hepdata.836

Data are presented for the reaction ep → ep π 0 at a nominal four-momentum transfer squared of 0.5 (GeV/ c ) 2 . The data were obtained using an extracted electron beam from NINA and two magnetic spectrometers for coincidence detection of the electron and proton. Details are given of the experimental method and the results are given for isobar masses in the range 1.19 – 1.73 GeV/ c 2 .

Measurement of the polarization of the recoil neutron from the photoproduction of charged pions on hydrogen

Althoff, K.H. ; Piel, H. ; Wallraff, W. ; et al.
Phys.Lett.B 26 (1968) 640-641, 1968.
Inspire Record 1099537 DOI 10.17182/hepdata.29335

The polarization of the recoil neutron in the reaction γ + p → π + + n has been measured for a pion c.m.-angle of 90° and a photon energy of 390 MeV. Hydrogen was used as the polarization analyser.

Backward scattering of positrons and electrons on protons

Bouquet, B. ; Benaksas, D. ; Grossetête, B. ; et al.
Phys.Lett.B 26 (1968) 178-180, 1968.
Inspire Record 1389620 DOI 10.17182/hepdata.29320

The ratio R = σ (e + + p)/ σ (e − + p) of the elastic scattering cross-section detecting the recoil proton at 0 o in coincidence with the backward electron or positron was found to be R = 1.036 ± 0.018 at q 2 = 8 fm −2 , R = 1.079 ± 0.046 at q 2 = 32 fm −2 .

Measurement of the analyzing power $A_y$ in neutron-proton radiative capture at $E_n$ = 68 MeV

Tuccillo, M. ; Fritschi, D. ; Götz, J. ; et al.
Nucl.Phys.A 580 (1994) 253-262, 1994.
Inspire Record 1389770 DOI 10.17182/hepdata.36513

The vector analyzing power Ay for the reaction Full-size image (<1 K) has been measured at five angles between 60° and 140° in the lab at an incident neutron energy of 67.7 MeV. The measurement is of a presision never before acheived (ΔAy ⩽ 0.01, statistical) for this observable. This precision makes possible a quantitative comparison with meson-exchange theories, thus enhancing our understanding of the role of non-nucleonic degrees of freedom.

A phase shift analysis of the K<sup loc="post">+</sup>p elastic scattering at 780 MeV/c has been performed. The experimental differential cross section is best explained by a solution with dominant s wave, negative s wave phase shift (−42.7 ± 1 deg.) and small contributions of p and d waves.

Inspire Record 1389642 DOI 10.17182/hepdata.29204

The reaction e + p → e ′+ N ∗ was studied for four momentum transfers up to 2.34 (GeV/ c ) 2 in the region of the 1236 MeV isobar. An analysis of the data in terms of the cross sections σ T and σ L for the absorption of transverse and longitudinal photons is given for invariant masses of the final pion nucleon system W =1.220 GeV and W =1.350 GeV.
