    Spin and parity assignment in 152 Gd investigating octupole structures
    (University of Western Cape, 2008) Bvumbi, Suzan Phumudzo; Roux, D.G.; Mullins, S.M.; Sharpey-Schafer, John F.
    The high-spin states of the nucleus 152Gd have been populated via the 152Sm (α, 4n) 152Gd fusion-evaporation reaction at a beam energy of 45MeV. The emitted γ rays were observed with the AFRODITE spectrometer array. The previously known decay scheme of 152Gd was extended. Directional Correlation from Oriented states of nuclei (DCO) and linear polarization measurements were performed in order to assign spins and parities in the 152Gd decay scheme. An alternative interpretation of the first excited Kπ = 0+ band, previously considered to be a β-vibration is discussed.
