Measurement of the gamma-V Coupling Constants and sigma-T (Vd) from Coherent gamma-d Interactions at 7.5-GeV

We have measured the total and differential cross-sections for coherently photoproduced ϱ, ω and ϱ′ on deuterium at 7.5 GeV. Using VDM relations, we have obtained γ ω 2 / γ ϱ 2 = 7.1 ± 1.5, σ T ( ϱ d) = (54 ± 2) mb and σ T ( ω d) = (56 ± 5) mb. Assuming the amplitude for ϱ′ production via an intermediate ϱ 0 to be small and that the amplitudes for ϱp and ϱ′p elastic scattering are comparable, we found γ ϱ ′ 2 / γ ϱ 2 = 6.0 ± 1.2 and σ T ( ϱ ′d) = (47 ± 6) mb.

At the 500 MeV electron synchrotron in Bonn differential cross sections of the reaction γ + d → π 0 + d were measured in forward pion c.m. angles and photon energies between 340 and 420 MeV.

Study of rho0 Production in gamma d, gamma p and gamma n Reactions at 7.5-GeV/c Using Linearly Polarized Photon Beam

Alexander, G. ; Gandsman, J. ; Levy, A. ; et al.
Nucl.Phys.B 69 (1974) 445-453, 1974.
Inspire Record 94508 DOI 10.17182/hepdata.32344

The reaction γ d→d ππ , γ p→p ππ and γ n→n ππ were studied in the SLAC 82″ deuterium filled bubble chamber, exposed to a linearly polarized photon beam of 7.5 GeV. All three reactions are dominated by ϱ 0 production. The differential cross section has a slope of ∼6.5 GeV −2 for nucleon reactions and a slope of ∼27 GeV −2 for coherent deuteron reactions. The behaviour of the density matrix elements shows that ϱ production conserves s -channel c.m.s. helicity and is dominated by natural parity exchange.

Total and Partial gamma d, gamma n and gamma p Cross-Sections at 7.5-GeV

Alexander, G. ; Gandsman, J. ; Jacobs, L.D. ; et al.
Nucl.Phys.B 68 (1974) 1-11, 1974.
Inspire Record 94509 DOI 10.17182/hepdata.32388

Total and partial γd, γp and γn reactions were studied in the SLAC 82 inch deuterium-filled bubble chamber, which was exposed to a linearly polarized photon beam at an energy of 7.5 GeV. We report total, topological and channel cross sections for these reactions. The γn average charge multiplicity was found to be one unit of charge less than the γp average charge multiplicity. The isoscolar-isovector interference term as calculated by comparing the γp charge symmetric reactions is found to be small.
