Gamma ray spectroscopic analysis around the N=104 mid-shell for 176,177Yb and 182W nuclei
Περίληψη
Even-even Yb and W isotopes around the N=104 mid-shell region are known to present deformation. The ground-band states of these nuclei are well described by the SU(3) symmetry, indicating a rigid-rotor character. Excited states of even-even isotopes in the region, namely 176Yb and 182W, were populated through Coulomb excitation and fusion-evaporation reactions, in an experiment performed at IFIN-HH in Măgurele, Romania. The gamma-spectroscopy of these nuclei will be presented in this contribution. Additionally, gamma spectroscopy results for the even-odd 177Yb nucleus, populated by the 1n-transfer reaction mechanism, will be presented. Contradictory to the collective description of the ground-band excitations in 176Yb and 182W isotopes, the excited states of this nucleus can be described by single-particle excitations. The gamma-spectroscopy analysis of this data contributes to the evaluation of the available data in this mass region, while ongoing work is expected to provide further insights for the nuclear structure of these rare-earth isotopes.
