摘要：

The energy levels and Lambda Lambda bond energy of the double-Lambda hypernucleus Be-11 are calculated considering two- and three-nucleon forces. The interactions between the constituent particles are contact interactions that reproduce the low-energy binding energy of the nuclei. Effective action is constructed to involve the three-body forces. In this paper, we compare the binding energy result that is obtained with the experimental and other modern nucleon-nucleon potentials. The results of all the schemes agree very well, showing the high accuracy of our present ability to calculate the many-nucleon bound state with three-body forces. The experimental value of B-Lambda Lambda(Be-11(Lambda Lambda))=20.83 MeV seems to be more compatible with our calculated value of B-Lambda Lambda(Be-11(Lambda Lambda))=19.31 MeV in comparison with the calculated result of 18.23 MeV by Hiyama et al.
