Isospin symmetry investigation of the proton-unbound nucleus T = 3/2 55Cu
(2025) International Conference on Nucleus-Nucleus Collisions In Nuclear Physics A 1056.- Abstract
This study reports the status of the first in-beam γ-ray spectroscopic study of excited states in the exotic neutron-deficient Tz=-3/2 nucleus 55Cu. The nucleus was produced via knock-out reactions at the Radioactive Isotope Beam Factory, located at the RIKEN-Nishina Center. Several γ-ray transitions were detected using the DALI2+ γ-ray detector array. The comparison with isobaric analogue states in the mirror nucleus 55Fe will provide valuable insights into isospin-non-conserving effects beyond nuclear stability. The proton occupation of the 1p3/2 orbital is expected to play a significant effect on the orbital's charge radius due to the isovector monopole... (More)
This study reports the status of the first in-beam γ-ray spectroscopic study of excited states in the exotic neutron-deficient Tz=-3/2 nucleus 55Cu. The nucleus was produced via knock-out reactions at the Radioactive Isotope Beam Factory, located at the RIKEN-Nishina Center. Several γ-ray transitions were detected using the DALI2+ γ-ray detector array. The comparison with isobaric analogue states in the mirror nucleus 55Fe will provide valuable insights into isospin-non-conserving effects beyond nuclear stability. The proton occupation of the 1p3/2 orbital is expected to play a significant effect on the orbital's charge radius due to the isovector monopole polarizability, which can be linked to the measured mirror energy differences.
