Within the SEASTAR III campaign at the Radioactive Isotope Beam Factory, at the RIKEN Nishina Center, neutron-rich isotopes in the vicinity of ⁵³K were produced from the fragmentation of the primary ⁷⁰Zn beam on a ⁹Be target. After nucleon knockout reactions on the secondary liquid hydrogen MINOS target the known γ rays of the neutron-rich ⁵⁵Sc isotope were observed (shown in this proceedings) and γ rays from ⁵⁷,⁵⁹Sc isotopes have been identified for the first time. The evolution of the occupied nucleon orbitals of these nuclei in the ground and excited state is investigated under the prism of the tensor force.
