    Notes: Abstract: Excited states of the 119Xe nucleus have been studied by using in-beam γ-ray spectroscopy with the 107Ag ( 16O, p3n) 119Xe fusion-evaporation reaction at a beam energy of 85 MeV. The level scheme of 119Xe has been derived from γ-γ coincidence and γ-γ angular correlation analyses. We have, for the first time, established the second negative-parity favored and unfavored states built on the 11/2- state, namely the yrare rotational bands in 119Xe. In contrast to the behavior of the yrast bands where the favored states are lying lower in energy, the yrare favored states were observed to lie above the unfavored band. Such a signature inversion in 119Xe is changed to be normal at I = 12?.

    Rotational bands in115Sb (1995)

    Notes: Abstract High-spin states of115Sb were studied by inbeamγ-ray spectroscopy using the89Y (29Si, 2pn) fusionevaporation reaction at a beam energy of 108 MeV. The experiments includedγ-γ coincidence and directional correlation of oriented nuclei (DCO) ratio measurements using six BGO Compton suppressed Ge detectors. An intruderΔJ=2 rotational band has been identified for the first time and it is interpreted as the h11/2 proton coupled to a two particle-two hole (2p − 2h) deformed state of the114Sn core. A ΔJ=1 rotational band based on the 2p − 1h, π{g 7 2/2 ⊗g 9 2/−1 }, configuration has been extended to the 29/2+ state at an excitation energy of 5241 keV.
