Probing three-nucleon force using nucleon-deuteron breakup reactions
- Duke Univ., Durham, NC (United States)
Possible evidence for the influence of three-nucleon forces (3NF) dates back to the observation that most realistic two-nucleon force models underpredict the triton binding energy by about 1 MeV. Though calculations which included 3NFs demonstrated that the triton binding energy problem could be remedied, they did not provide firm evidence of 3NFs, since the three-nucleon potentials used did not have rigid connections to realistic nucleon-nucleon (N-N) force models. To make the situation even more nebulous, the triton binding energy has been shown to be strongly sensitive to the strength of the N-N tensor force. In an effort to find three-nucleon (3N) observables that are insensitive to details of the N-N force and which might exhibit some sensitivity to 3NF effects, attention is now being focused on 3N continuum observables. In this paper the authors present their results for kinematically complete cross-section measurements of the space-star, coplanar-star and collinear configurations in neutron-deuteron (n-d) breakup at 13.0 MeV. These data are a subset of the results obtained in a recent experiment in which cross sections for 46 configurations were measured simultaneously. The experimental techniques will be described. These new data will be compared to previous n-d data, to proton-deuteron data and to rigorous n-d calculations.
