EVIDENCE FOR AND EXPLICATION OF THE D-STATE IN FEW-NUCLEON SYSTEMS

A review is given of our current understanding of the D-state properties of the few-nucleon nuclei 2H, 3H, 3He, 4He, and 6Li. Emphasis is placed on the theoretical interpretation of the latest empirical evidence, especially those experiments involving polarized beams. An attempt is made to provide a coherent theoretical overview of our current understanding of the D-wave asymptotic normalization constants of the above few-nucleon systems. The aim is to tie the theoretical predictions of the ratio of the D-wave to S-wave asymptotic normalization constants to the presence of the two-nucleon tensor force. Following this discussion is an assessment of what has been learned about the D-state in the above few-nucleon nuclei from radiative capture reactions. The review closes with a summary of our current understanding of the D-state in few-nucleon systems and a projection of possible future directions
