Detailed α-decay study of 180Tl

Ondertitel:Detailed alpha-decay study of Tl-180

A detailed alpha-decay spectroscopy study of Tl-180 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 Tl-180. Fine-structure alpha decays to excited levels in the daughter Au-176 were identified and an alpha-decay scheme of Tl-180 was constructed based on an analysis of alpha-gamma and alpha-gamma -gamma coincidences. Multipolarities of several gamma-ray transitions deexciting levels in Au-176 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.
