Ab initio shell model with a chiral-symmetry-based three-nucleon force for the p-shell nuclei
The ab initio no-core shell model (NCSM) is extended to include a realistic three-body interaction in calculations for p-shell nuclei. They present results of first applications using the Argonne V8' nucleon-nucleon (NN) potential and the Tucson-Melbourne TM'(99) three-nucleon interaction (TNI). In addition to increase of binding energy, they observe a trend toward level-ordering and level-spacing improvement in comparison to experiment. With the TNI they obtain a correct ground-state spin for {sup 10}B contrary to calculations with NN potentials only. They also investigate neutrino-{sup 12}C exclusive cross sections and muon capture on {sup 12}C. They show that realistic nucleon-nucleon interactions underpredict the experimental cross sections by a factor of two or more. By including the TNI a much better agreement with experiment is achieved along with an encouraging trend.
