“…Level lifetimes were extracted from each angular distribution using the Doppler-shift attenuation method with the methodology described in Refs. [11,12]. The γ-ray excitation functions of the levels in 106 Pd and 106 Cd were measured over a range of neutron energies from 2.0 to 3.8 MeV in 0.1-MeV steps, at 90 • with respect to the beam direction.…”

Excited levels of 128 Te to 3.3 in MeV excitation have been studied using γ-ray spectroscopy following inelastic scattering of accelerator-produced neutrons. Spectroscopic information, including transition energies, level spins, E2/M1 multipole-mixing ratios, and γ-ray branching ratios, was determined from γ-ray excitation functions measured from E n = 2.15 to 3.33 MeV in 90 keV increments, γ-ray angular distributions measured at E n = 2.2, 2.8, and 3.3 MeV, and γγ coincidences measured at E n = 3.6 MeV. Lifetimes of levels in 128 Te were deduced using Doppler-shift attenuation techniques. Absolute transition probabilities were determined for many levels and compared to interacting boson model and particle-core coupling model calculations to identify few particle and collective structures; states exhibiting the decay characteristics expected for two-phonon, mixed-symmetry, and quadrupole-octupole coupled states are identified.

Doubly magic nuclei and their near neighbours serve as an ideal testing ground for the nuclear shell model, and, consequently, enable us to define effective nuclear interactions. Collective states in nuclei near 56 Ni can be attributed to multiparticle-multihole excitations from the 1 f 7/2 to the 2p 3/2 , 1 f 5/2 and 2p 1/2 orbits across the N, Z = 28 shell gap. These features are usually associated with shape coexistence. Properties of excited 0 + states, as well as E0 and E2 transition strengths are sensitive probes of the underlying nuclear structure. The aim of this work is to identify and characterize excited 0 + states and corresponding E0 transitions in 54,56,58 Fe to search for shape coexistence around the N, Z = 28 shell closure. In order to obtain experimental information, E0 transitions between the lowest excited 0 + states and ground states were measured for the stable even-even iron isotopes using the superconducting electron spectrometer ,"Super-e", at the Australian National University. Additional information on angular distributions, angular correlations, and γ − γ coincidences was obtained with the CAESAR detector array (at ANU) under the same experimental conditions. In order to deduce E0 strengths, the experimental data were evaluated with lifetime information from Doppler-shift attenuation measurements following inelastic neutron scattering, carried out at the University of Kentucky.
