摘要
The nuclear structure of Te-127 has been investigated with the Te-126(n,gamma)Te-127 reaction using thermal neutrons and with the Te-126((d) over right arrow ,p)Te-127 reaction at E-d = 20 MeV. More than 150 levels were identified already below 3.6 MeV excitation energy, in most cases including spin, parity and gamma-decay. The gamma-decay scheme after neutron capture is essentially complete containing about 100% of the population of the 11/2(-) isomer and of the ground state. The thermal neutron capture cross section and isomer production of the 11/2- state at 88.3 keV were determined to be 0.38(4)b and 0.063(5)b, respectively. The experimental level scheme is compared with predictions of the Interacting Boson-Fermion Model (IBFM) and of the Quasiparticle Phonon Model (QPM).
