Investigation of the neutron-deficient isotope 123Ba
N. Yoshikawa1, J. Gizon1, A. Gizon1

High-spin levels in 123Ba have been produced in the 114 Sn(12C, 3n) reaction and studied by in-beam γ-ray spectroscopic techniques. Only one strongly populated band structure has been identified and explained as an odd-parity level system based on a 7/2 - state generated by the coupling of an h11/2 neutron-hole to a prolate-type triaxial core. Comparisons with heavier odd-A Ba isotopes and N = 67 isotones are made.
