Structure of 186Ir and decoupling phenomena in doubly-odd deformed nuclei
States of 186Ir, excited through several (HI, xn) reactions, were studied using in-beam γ-ray spectroscopy techniques. A completely new high-spin level scheme, comprising several rotational bands, is presented. The positive-parity ΔI = 2 ground-state band is possibly a first example of a hitherto un...

| Sumario: | States of 186Ir, excited through several (HI, xn) reactions, were studied using in-beam γ-ray spectroscopy techniques. A completely new high-spin level scheme, comprising several rotational bands, is presented. The positive-parity ΔI = 2 ground-state band is possibly a first example of a hitherto unreported scheme called double decoupling associated with a proton and neutron both occupying Ω = 1 2 orbits of decoupling parameters larger than unity. A prominent ΔI = 1 negative-parity structure is interpreted as the πh9 2 ⊗ νi13 2 band known in Tl isotopes but in a prolate-deformed situation. © 1985. |
