Abstract
Experiments are underway at the Triangle Universities Nuclear Laboratory (TUNL) that provide data for evaluating calculations based on low-energy QCD theories, e.g., effective field theory formulations of two-nucleon and three-nucleon interactions, chiral-perturbation theory, and Lattice QCD. Few-nucleon reaction measurements are carried out using the monoenergetic polarized gamma-ray beam at the High Intensity Gamma-ray Source (HI\(\gamma \)S) and the neutron beams at the tandem laboratory. Experiments in nucleon structure are performed at HI\(\gamma \)S. In this paper we present the status of recent few-nucleon experiments that measure the cross sections for neutron-neutron quasifree scattering in neutron-deuteron breakup and for photodisintegration of \(^3\)He.
