The low-lying structure of 15 C has been investigated via the neutron-removal 16 C (d, t) reaction. Along with the known bound neutron sd-shell states, unbound p-shell hole states have been observed. The excitation energies and the deduced spectroscopic factors of the cross-shell states are an important measure of the [(p)− 1 (s d) 2] neutron configurations in 15 C. Our results show a very good agreement with shell-model calculations using the SFO-tls interaction for 15 C. However, this same interaction predicted energies that were too low for the corresponding hole states in the N= 9 isotone 17 O and adjustment of the p-sd and sd-sd monopole terms was required to match the 17 O energies. In addition, the excitation energies and spectroscopic factors have been compared to the first calculations of 15 C with the ab initio self-consistent Green's function method employing the NNLO s a t interaction. The results show the sensitivity to the size of the N= 8 shell gap and highlight the need to go beyond the current truncation scheme.
