Coexistence of Vibrational and Quasiparticle Structures in Neutron-Deficient 114,115,116,117Te

摘要: Excited states in 114-117Te were populated the bombardment of 114,116Sn targets with 3He ions at energies Elab = 20.9-27.5 MeV. The subsequent de-excitation was studied using in-beam spectroscopic methods, including measurements γ-ray excitation, γ-γ coincidences, γ-RF timing, angular distributions and conversion electrons. States momenta up to J 12 h observed, but no isomers T1/2 1 ns located. excited structures are discussed terms vibrational bands coupled one- two-quasiparticle shell-model structures. systematical behaviour Te isotopes is mass range A 115-123 for odd, 112-134 even isotopes.
