Structure of 191Pb from α- and β-decay spectroscopy

Complementary studies of 191Pb have been made in the β decay of 191Bi at LISOL (CRC) and in the α decay of 195Po at ISOLDE (CERN). Fine structures in the α decay of the low-spin and high-spin isomers of 195Po have been fully resolved. Identification of the parent state is made possible via isomer selection based on narrow-band laser frequency scanning. The α-particle and γ -ray energies have been determined with greater precision. New α-particle and γ -ray energies are identified. Branching ratios in the decay of 195Po and 191Pb have been examined.status: publishe
