11 Dec 2001 | | Journal: | Phys.Rev. C65 (2002) 054003 | | Subject: | nucl-th | | Abstract: | The Faddeev-Yakubovsky equations for the alpha-particle are solved. Accurate results are obtained for several modern NN interaction models, which include charge-symmetry breaking effects in the NN force, nucleon mass dependences as well as the Coulomb interaction. These models are augmented by three-nucleon forces of different types and adjusted to the 3N binding energy. Our results are close to the experimental binding energy with a slight overbinding. Thus there is only little room left for the contribution of possible 4N interactions to the alpha-particle binding energy. We also discuss model dependences of the binding energies and the wave functions. | | Source: | arXiv, nucl-th/0112026 | | Services: | Forum | Review | PDF | Favorites | |
