Three-nucleon forces and the spectroscopy of neutron-rich calcium isotopes⋆ — •Johannes Simonis1,2, Jason D.

We study excited-state properties of neutron-rich calcium isotopes based on chiral two- and three-nucleon interactions. Our results are based on a many-body perturbation theory approach combined with large-scale diagonalizations. In particular, we will focus on the impact of 3N forces on electromagnetic transitions including the investigation of theoretical uncertainties by means of cutoff variation and different sets of low-energy constants.
