Photoproduction of neutral pions off neutrons in the energy region between 500 mev and 900 mev

Hemmi, Y. ; Inagaki, T. ; Kikuchi, R. ; et al.
Nucl.Phys.B 55 (1973) 333-362, 1973.
Inspire Record 84140 DOI 10.17182/hepdata.32564

The differential cross sections for the reaction γ + n → π 0 + n have been measured at pions angles of 45°, 60°, 105°, 120° and 140° in the c.m.s. for photon energies of 500–900 MeV. Both π 0 meson and recoil neutron from a liquid deuterium target were detected with a pair of Čerenkov counters combined with lead spark chambers and a hodoscope consisting of 16 modules of plastic scintillation counters.

Measurement of the pi- p ---> n pi0 and pi- p ---> n gamma differential cross-sections near the resonance p(11)(1460)

Cheze, J.B. ; Codreanu, N. ; Hamel, J.L. ; et al.
Nucl.Phys.B 72 (1974) 365-375, 1974.
Inspire Record 94658 DOI 10.17182/hepdata.7810

The π − p→n γ and π − p→n π ° differential cross sections have been measured for −0.9< cos θ ∗ <−0.45 (θ ∗ c.m. scattering angle) at 475 MeV/ c and 550 MeV/ c incident momenta. The π − p→n γ measurement is a good check of the detailed balance principle in the electromagnetic interactions of hadrons at these energies and is in good agreement with Walker's analysis. On the other hand the π − p→ π °n extrapolated values of 180° allows one to verify that the phases of the A 1 2 and A 3 2 amplitudes are equal.

Observation of an Anomalous Structure in Proton Polarization from Deuteron Photodisintegration

Kamae, T. ; Arai, I. ; Fujii, T. ; et al.
Phys.Rev.Lett. 38 (1977) 468, 1977.
Inspire Record 110084 DOI 10.17182/hepdata.21021

Proton polarization in γd→pn has been measured at c.m. angle around 90° and photon energies from 325 to 725 MeV. The polarization increases sharply with the photon energy, reaching a high maximum of (-80±8)% around 500-550 MeV. Such a high polarization with a sharp energy dependence seems to indicate a new effect in the dibaryon system.

Measurement of the Proton Polarization in Deuteron Photodisintegration at Photon Energies Between 350-MeV and 700-MeV

Kamae, T. ; Arai, I. ; Fujii, T. ; et al.
Nucl.Phys.B 139 (1978) 394-412, 1978.
Inspire Record 135594 DOI 10.17182/hepdata.35048

The proton polarization in the γ d → pn reaction has been measured at a c.m. angle of 90° and photon energies between 350 and 700 MeV, using a carbon polarimeter. The magnitude of the polarization shows a sharp energy dependence with a peak of about −80% at around 500–550 MeV. This feature cannot be explained by conventional models and seems to indicate a new mechanism in the dibaryon system.
