Abstract
The odd- nucleus was studied using combined -ray and conversion-electron in-beam spectroscopy. Besides the previously observed rotational band based on the configuration, another rotational structure has been identified using coincidences. The use of electron spectroscopy allowed the rotational bands to be observed over a larger rotational frequency range. Using the transition intensities that depend on the gyromagnetic factor, a single-particle configuration has been inferred for this band, i.e., the ground-state band. A physical background that dominates the electron spectrum with an intensity of was well reproduced by simulating a set of unresolved excited bands. Moreover, a detailed analysis of the intensity profile as a function of the angular momentum provided a method for deriving the orbital gyromagnetic factor, namely for the ground-state band. The odd- was studied using -ray in-beam spectroscopy. Evidence for octupole correlations resulting from the mixing of the and Nilsson orbitals were found in both . A surprising similarity of the ground-state band transition energies with those of the excited band of has been discussed in terms of identical bands. Skyrme-Hartree-Fock-Bogoliubov calculations were performed to investigate the origin of the similarities between these bands.
