Abstract

The internal transition decay and ? decay of the T1/2=53.3ms, 9/2-isomeric state in the neutron-deficient isotope, Tl183, have been studied using the Resonance Ionization Laser Ion Source and the Windmill detection setup at the ISOLDE facility at CERN. Clean samples of Tl183m were produced by selective laser ionization and subsequent mass separation. An internal transition cascade of 356.5-272.2 keV ? rays has been identified. Multipolarities of these transitions have been determined by means of simultaneous ?-ray and conversion-electron spectroscopy. Improved data for the fine structure of the Tl183m?Au179 decay were deduced. This involves a 6058 keV ?-decay transition, which populates a previously unknown state in Au179, that is tentatively assigned as a (9/2-). It is interpreted as a coupling of the 1h9/2 proton-intruder with the excited 0+ state in the Pt178 core.
