“…This was subsequently confirmed by two independent measurements [8,9]. The observation was demonstrated to provide evidence for the contribution of the relativistic spin-orbit dipole operator even at photon energies well below 50 MeV [10,11]. These are but two examples that illustrate the significant role played by low-energy neutron-proton radiative capture and threshold deuteron photodisintegration experiments in developing our understanding of nuclear physics in terms of the physically observable hadrons, the baryons and mesons, and their interactions.…”

The importance of n-p radiative capture, utilizing polarized cold neutrons, as a means of measuring the weak pion coupling constant is reviewed. Parity conserving processes of the form k γ · (s n × k n ) can contribute to the s n · k γ photon asymmetry in any such experiment, if the apparatus is not perfectly symmetric. For an incident laboratory neutron energy of 0.003 eV a value of A P C γ = 0.67 × 10 −8 is obtained for two different potential models (Argonne AV14 and Nijmegen Reid93). Serving as an extreme test case, the Reid soft core potential yields 0.61 × 10 −8 , close to the result of the contemporary forces. Implications for extracting the weak pion coupling constant and for monitoring the beam polarization are discussed.

Precise measurements of the deuteron vector analyzing power A d y and the tensor analyzing power Ayy of the 1 H( d, γ) 3 He-capture reaction have been performed at deuteron energies of 29 MeV and 45 MeV. The data have been compared to theoretical state-of-the-art calculations available today. Due to the large sensitivity of polarization observables and the precision of the data light could be shed on small effects present in the dynamics of the reaction.

“…In addition, we also take into account the relativistic spin-orbit current as most important relativistic contribution of leading order. This relativistic contribution is quite important in photodisintegration of the deuteron, even at low energies [4,5].…”

Photodisintegration of the deuteron above π threshold is studied in a coupled channel approach including N ∆ and πd channels with consideration of pion retardation in potentials and exchange currents. A much improved description of total and differential cross sections in the energy region between π threshold and 400-450 MeV is achieved. With respect to polarization observables, the description of the linear photon asymmetry and the proton polarization remains problematic.
