Abstract
The first spectroscopy of K was investigated via in-beam -ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory after one-proton and one-neutron knockout from Ca and K beams impinging on a 15-cm liquid hydrogen target at 230~MeV/nucleon. The energy level scheme of K was built using single and - coincidence spectra. The spins and parities of the excited states were established based on momentum distributions of the fragment after the knockout reaction and based on exclusive cross sections. The results were compared to state-of-the-art shell model calculations with the SDPF-Umod interaction and ab initio IMSRG calculations with chiral effective field theory nucleon-nucleon and three-nucleon forces.
