Abstract

The first spectroscopy of K-52 was investigated via in-beam gamma-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory after one-proton and one-neutron knockout from Ca-53 and K-53 beams impinging on a 15-cm liquid hydrogen target at approximate to 230 MeV/nucleon. The energy level scheme of K-52 was built using single gamma and gamma-gamma 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 inmedium similarity renormalization group calculations with chiral effective field theory nucleon-nucleon and three-nucleon forces.
