Abstract
A detailed alpha-decay spectroscopy study of 180Tl has been performed at ISOLDE (CERN). Z-selective ionization by the Resonance Ionization Laser Ion Source (RILIS) coupled to mass separation provided a high-purity beam of 180Tl. Fine-structure alpha decays to excited levels in the daughter 176Au were identified and an alpha-decay scheme of 180Tl was constructed based on analysis of alpha-gamma and alpha-gamma-gamma coincidences. Multipolarities of several gamma-ray transitions deexciting levels in 176Au were determined. Based on the analysis of reduced alpha-decay widths, it was found that all alpha decays are hindered, which signifies a change of configuration between the parent and all daughter states.
