“…The peak near the end point arises from the radiative capture process p+d~He+y. The magnitude of this cross section and its energy have been verified by comparing with previous measurements by Pikar et al at 150 and 200 MeV[20]. The measurement by Pikar et al was a coincidence experiment detecting both the He as well as the emitted gamma ray.…”

“…In general, the results for both methods showed small variations overall (less than 10%%uo) with largest difference at 30%%uo for the MeV; also shown is a comparison of the radiative capture peak p +d~'He+ y. The capture peak is generated by using the value for the radiative capture process measured by Pikar et al [20] and a procedure described in the text.…”

Energy spectra and angular distributions have been measured for high energy gamma rays (E~~2 0 MeV) from the p+d reaction at 145 and 195 MeV. Gamma rays were observed up to the maximum energy allowed by kinematics. A comparison is made with previous measurements for the p+d system at 140, 197, and 200 MeV. Below the free pny threshold the general shape of the energy spectra and angular distributions are in reasonable agreement with a recent calculation of the free pny elementary process. However, the magnitude of the predicted cross section is not in good agreement with the present data.PACS number(s): 25.40.h

A big spectrum of processes induced by real and virtual photons on the 3 He and 3 H nuclei is theoretically investigated through many examples based on nonrelativistic Faddeev calculations for bound and continuum states. The modern nucleon-nucleon potential AV18 together with the threenucleon force UrbanaIX is used. The single nucleon current is augmented by explicit π-and ρ-like two-body currents which fulfill the current continuity equation together with the corresponding parts of the AV18 potential. We also employ the Siegert theorem, which induces many-body contributions to the current operator. The interplay of these different dynamical ingredients in the various electromagnetic processes is studied and the theory is compared to the experimental data.Overall we find fair to good agreement but also cases of strong disagreement between theory and experiment, which calls for improved dynamics. In several cases we refer the reader to the work of other groups and compare their results with ours. In addition we list a number of predictions for observables in different processes which would challenge this dynamical scenario even more stringently and systematically.

“…In contrast to the elastic Nd scattering data, however, the experimental data base on radiative Nd capture is much poorer. In particular, in the intermediate energy range (∼50-200 MeV/nucleon), below the pion-production threshold, the available data [12,13,14,15] are scarce and in general lack precision or completeness in angular coverage and the number of observables.…”

A radiative deuteron-proton capture experiment was carried out at KVI using polarized-deuteron beams at incident energies of 55, 66.5, and 90 MeV/nucleon. Vector and tensor-analyzing powers were obtained for a large angular range. The results are interpreted with the help of Faddeev calculations, which are based on modern two-and three-nucleon potentials. Our data are described well by the calculations, and disagree significantly with the observed tensor anomaly at RCNP.
