Abstract

An experiment utilizing a polarized 3He target and other 3-nucleon experiments at the Indiana University Cyclotron Facility are discussed. The 3 He ( p , pN) reaction has been used to investigate the spin dependent momentum distributions of protons and neutrons in 3He. It was found that with large momentum transfer the PWIA is valid, thus allowing extraction of the distributions directly from the data. A similar experiment is currently under preparation to investigate the spin structure of the deuteron via the 2 H ( p , pN) reaction. Other experiments will study n-d and p-d breakup spin observables in final state interaction kinematics where intermediate energy Faddeev calculations predict large 3-body force effects.
