“…lower than the theoretical predictions; the findings reported by Sagara at this conference [23] are consistent with these results. Long-range 3NIs that are not included in current calculations is a possible cause of the discrepancy between data and theory for the SST in nucleon-deuteron breakup.…”

Abstract. The central goal of few-nucleon research at the Triangle Universities Nuclear Laboratory (TUNL) is to perform measurements that contribute to advancing ab-initio calculations of nuclear structure and reactions. The program aims include evaluating theoretical treatments of few-nucleon reaction dynamics through strategically comparing theory predictions to data, determining properties of the neutron-neutron interaction that are not accessible in two-nucleon reactions, and searching for evidence of longrange features of three-nucleon interactions, e.g., spin and isospin dependence. This paper will review studies of three-and four-nucleon systems at TUNL conducted using unpolarized and polarized neutron beams. Measurements of neutron-induced reactions performed by groups at TUNL over the last six years are described in comparison with theory predictions. The results are discussed in the context of the program goals stated above. Measurements of vector analyzing powers for elastic scattering in A=3 and A=4 systems, differential cross sections for neutron-deuteron elastic scattering and neutrondeuteron breakup in several final-state configurations are described. The findings from these studies and plans for the coming three years are presented in the context of worldwide activities in this front, in particular, research presented in this session.

“…Three presentations in this session are examples of such investigations. Sagara et al [23] describe the energy dependence of the space-star (SST) in pd breakup at proton energies below 20 MeV. They found that the ratio of the cross-section data to calculations is nearly constant with the data being about 8% lower than theory.…”
