    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?.

    Energy damping feature in light heavy-ion reactions (1989)
    Springer
    The European physical journal 333 (1989), S. 379-388

    Notes: Abstract The energy damped reaction products from37Cl+12C,27Al,48Ti and16O+48Ti were measured over a wide range of angles (typically 18°〈θ lab〈70°), incident energies (160 〈E lab(37Cl)〈200 MeV,E lab(16O)=118 MeV) and charges Z, including two systems (37Cl+37Al and16O+48Ti) which lead to the same compound nucleus64Zn with the same excitation energy and comparable angular momenta. The angular dependences of total kinetic energy (TKE) and dσ/dθ were decomposed into two components (forward peaked and nearly constant at backward angles), and the elemental TKE and cross sections were derived. The backward components of37Cl+27Al and16O+48Ti exhibit very different Z-distributions, indicating that the fragments do not originate from compound nucleus decay. The results can be understood in terms of an energy damping process.
