Abstract

Chiral two- and three-nucleon interactions are studied in few-nucleon systems. We investigate the cut-off dependence and convergence with respect to the chiral expansion. It is pointed out that the spectra of light nuclei are sensitive to the three-nucleon force structure. As an example, we present calculations of the 1⁺ and 3⁺ states of ⁶Li using the no-core shell model approach. The results show contributions of the next-to-next-to leading order terms to the spectra, which are not correlated to the three-nucleon binding energy prediction.
