Elastic scattering of 2.0 gev/c negative pions off protons

Tuli, S.K. ;
Nucl.Phys.B 12 (1969) 79-88, 1969.
Inspire Record 56104 DOI 10.17182/hepdata.35518

An experimental study of the elastic scattering of negative pions off protons at 2.0 GeV/ c is presented. The differential cross section is fitted to a polynomial in cos θ c.m. and the forward angular region as a diffraction peak. The results are compared with those from other bubble chamber experiments at neighbouring energies and discussed in terms of optical model and possible exchange trajectories.

DCS for π − p elastic scattering from 1.2 to 3.0 GeV/ c and phase shift analysis

Aplin, P.S. ; Cowan, I.M. ; Gibson, W.M. ; et al.
Nucl.Phys.B 32 (1971) 253-284, 1971.
Inspire Record 1104030 DOI 10.17182/hepdata.69638

Differential cross sections have been measured for π − p elastic scattering at laboratory momenta in the range 1.2 to 3.0 GeV/ c for the c.m. range 0.97 > cos θ ∗ > −0.98 . The corresponding mass range is 1.78 to 2.56 GeV/ c 2 . The data was obtained from a counter experiment in which the scattered pions and protons were detected in coincidence by arrays of scintillation counters.

Elastic electron scattering from c-12 and o-16

Sick, I. ; Mccarthy, J.S. ;
Nucl.Phys.A 150 (1970) 631-654, 1970.
Inspire Record 62489 DOI 10.17182/hepdata.37092

Electron scattering cross sections for carbon and oxygen between q = 1 fm −1 and 4 fm −1 are given. The data are analysed in terms of a phenomenological charge distribution and new information concerning the tail and the center of the charge distribution are obtained. The presence of dispersion effects appears to be necessary to explain the cross sections in the first diffraction minimum. The effect of a finite potential and short range correlations on the form factor are discussed.

Isospin invariance in the reaction n p ---> pi0 d

Wilson, S.S. ; Longo, M.J. ; Young, K.K. ; et al.
Nucl.Phys.B 33 (1971) 253-280, 1971.
Inspire Record 68508 DOI 10.17182/hepdata.33111

A measurement of the differential cross section for the reaction np→ π 0 d has been made at the Lawrence Radiation Laboratory 184-inch cyclotron. A neutron beam with kinetic energies up to 720 MeV was incident on a liquid hydrogen target. The angle and momentum of the deuterons were measured using an analyzing magnet and wire spark chambers with a magnetostrictive readout. Deuterons were separated from protons by time-of-flight. The photons from the decaying π 0 were not detected. The neutron energy was calculated from the measured deuteron angle and momentum.

Further evidence for the decay mode phi ---> eta gamma and measurement of the branching ratio gamma(phi ---> eta gamma)/gamma(phi ---> total)

Nucl.Phys.B 44 (1972) 605-617, 1972.
Inspire Record 75023 DOI 10.17182/hepdata.32854

The reaction π − p → ηφ has been studied at 1.8 GeV/ c incident pion momentum using the Bologna-CERN NBC set-up, in order to investigate the electromagnetic decay mode φ → ηγ . We observed (27 ± 6) events, yielding a branching ratio Γ(φ → ηγ) Γ(φ → total ) = (7.3 ± 1.9)% . The theoretical implications of this result are discussed.
