“…A wellknown level scheme would allow one to test both geometrical and algebraic nuclear models. It was shown earlier [1] that the low-energy levels can be partially understood as rotational bands on Nilsson orbits. Triaxial shape models can be used for the interpretation of the level scheme.…”

“…In the present work, a more detailed knowledge of the 194 Ir level structure is achieved than that in publication [1]. It has been enabled by new experimental results from the (d, p) and ( d, α) reactions and by the more complete evaluation of the earlier measured (n, γ ) and (n, e − ) spectra after thermal neutron capture.…”

“…Two publications [1,2] of the previous decade and the Nuclear Data Sheets [3] provide information on previous experimental studies. A theoretical description using the IBFFM model and the extended SUSY U ν (6/12)⊗U π (6/4) is given in Ref.…”

“…The energy calibration was done using well-known energies from Ref. [1] and the new (n, γ ) evaluation reported in this paper. The observed levels and their cross section at 20 • are listed in Table I.…”

Levels of two-particle and gamma bands in 192 Ir

“…Meanwhile, two large studies of the neighbouring 194 Ir nucleus have been published [3,4]. These studies have shown that there are two questions about 192 Ir which should be answered: (1) is 192 Ir structure more "deformed" than that of 194 Ir; (2) are there 11 − long-lived isomers in both 192 Ir and 194 Ir nuclei, as predicted by available proton-neutron configurations?…”
