Structure of the πg_7/2 404 7/2⁺ Band in Odd Proton Nucleus ¹²³I

High spin states of the odd proton nucleus ¹²³I have been populated in the reaction ¹¹⁶Cd(¹⁴N, 5n2p) at a beam energy of 65 MeV. Two previously known positive-parity ΔI = 2 sequences have been extended up to 31/2⁺ and 41/2⁺. In addition, a number of ΔI = 1 transitions linking the two ΔI = 2 sequences have been observed. It is suggested that both the ΔI = 2 sequences are built upon the oblate πg_7/24047/2⁺ Nilsson configuration.
