Description

Low-spin states of 186Ir populated through the β+/EC decay of 186Pt nuclei were studied using mass-separated sources and γ-ray and e- spectroscopic techniques. It is shown that the 2- isomeric state is located at an energy less than 1.5 keV above the 5+ ground state and that an isomeric transition with a relative intensity around 25% very likely exists. A completely new level scheme of 186Ir is also established. Most of the experimental levels are interpreted within the two-quasiparticle-plus-rotor model
