The angular distributions for deuteron photodisintegration have been measured in the energy region 140 – 400 MeV for recoil protons laboratory angles between 30° and 130°. The protons were analyzed in momentum with a magnetic spectrometer and detected by a counter hodoscope.

Differential cross section for the reaction $^2$H(γ,p)n from 133 to 158 MeV

Wallace, P.A. ; Annand, J.R.M. ; Anthony, I. ; et al.
Nucl.Phys.A 532 (1991) 617-633, 1991.
Inspire Record 1389763 DOI 10.17182/hepdata.36693

The cross section for the reaction 2H(γ, p)n has been measured at laboratory photon energies Eγ = 133−158 MeV and c.m. angles between 30° and 150°. The reaction was induced by a tagged bremsstrahlung photon beam incident on a liquid deuterium target. The uncertainty in the absolute cross sections is ⩽ 5%. There is now reasonable agreement between recent measurements in this energy region and the overall data set now defines the cross section sufficiently well to provide a test of current models of the reaction.

Complete angular distribution measurements of two-body deuteron photodisintegration between 0.5-GeV and 3-GeV.

Phys.Rev.C 70 (2004) 014005, 2004.
Inspire Record 650821 DOI 10.17182/hepdata.31633

Nearly complete angular distributions of the two-body deuteron photodisintegration differential cross section have been measured using the CLAS detector and the tagged photon beam at JLab. The data cover photon energies between 0.5 and 3.0 GeV and center-of-mass proton scattering angles 10-160 degrees. The data show a persistent forward-backward angle asymmetry over the explored energy range, and are well-described by the non-perturbative Quark Gluon String Model.

High resolution measurements of C-12 (gamma, n) and the implications for the (gamma, N) reaction mechanism at intermediate-energy

Andersson, B-E. ; Adler, J-O. ; Bulychjov, S.A. ; et al.
Phys.Rev.Lett. 71 (1993) 2703-2706, 1993.
Inspire Record 352385 DOI 10.17182/hepdata.19720

High resolution measurements of the reaction C12(γ,n) at Eγ∼58 MeV are presented. The distribution of strength to the resolved bound final states in C11 is compared with that of B11 obtained in previous analogous (γ,p) measurements and the implications for the theoretical description of (γ,N) reactions are discussed. These new results confirm the importance of two-nucleon effects in intermediate energy photon absorption and highlight inadequacies in state-of-the-art microscopic calculations of (γ,N) reactions.

Two-body disintegration of the deuteron with 0.8-GeV to 1.8-GeV photons

Freedman, S.J. ; Geesaman, D.F. ; Gilman, Ronald A. ; et al.
Phys.Rev.C 48 (1993) 1864-1878, 1993.
Inspire Record 365233 DOI 10.17182/hepdata.26023

The differential cross section for the reaction H2(γ,p)n has been measured at several center-of-mass angles ranging from 50° to 143° for photon energies between 0.8 and 1.8 GeV. The experiment was performed at the SLAC-NPAS facility with the use of the 1.6 GeV/c spectrometer to detect the high energy protons produced by a bremsstrahlung beam directed at a liquid deuterium target. Contributions from concurrent disintegration by the residual electron beam were determined by measuring the proton yield without the Cu photon radiator. At angles not very far from 90°, the energy dependence of the cross sections is consistent with predictions of scaling using counting rules for constituent quarks. At least one theoretical calculation based on a meson-baryon picture of the reaction is able to reproduce the magnitude and energy dependence of the 90° cross section. The angular distribution exhibits a large enhancement at backward angles at the higher energies.

Measurements were performed for the photodisintegration cross section of the deuteron for photon energies from 1.6 to 2.8 GeV and center-of-mass angles from 37° to 90°. The measured energy dependence of the cross section at θc.m.=90° is in agreement with the constituent counting rules.

Experimental Investigation of the Deuteron Photodisintegration in the $\Delta$ Resonance Region

Arends, J. ; Gassen, H.J. ; Hegerath, A. ; et al.
Nucl.Phys.A 412 (1984) 509-522, 1984.
Inspire Record 190187 DOI 10.17182/hepdata.50236

Differential cross sections for the deuteron photodisintegration process were measured for photon energies between 200 and 440 MeV using the tagged photon beam facility of the Bonn 500 MeV synchrotron. At eight angles between 18° and 145° charged particles were detected simultaneously in time-of-flight spectrometers consisting of scintillation counters. Above the resonance region the measured cross sections agree fairly well with earlier results, whereas there are larger discrepancies at low photon energies.
