abstract = {Background: The evolution of shell structure around doubly magic exotic nuclei is of great interest in nuclear physics and astrophysics. In the ‘southwest’region of Ni 78, the development of deformation might trigger a major shift in our understanding of explosive nucleosynthesis. To this end, new spectroscopic information on key close-lying nuclei is very valuable.
Purpose: We intend to measure the isomeric and β decay of Co 75, with one-proton and two-neutron holes relative to Ni 78, to access new nuclear structure information in Co 75 and its β-decay daughters Ni 75 and Ni 74.
Methods: The nucleus Co 75 is produced in relativistic in-flight fission reactions of U 238 at the Radioactive Ion Beam Factory in the RIKEN Nishina Center. Its isomeric and β decay are studied exploiting the BigRIPS and EURICA setups.
Results: We obtain partial β-decay spectra for Ni 75 and Ni 74, and report a new isomeric transition in …},
