Abstract.

The α-decay fine structure of 210-214Fr has been studied by α-γ-coincidence measurements. The nuclei were produced using the 12C on 209Bi reaction. Evaporation residues recoiling out of the target were separated in-flight by the velocity filter SHIP and stopped in a position-sensitive 16-strip PIPS-detector in order to study their subsequent decays. In the present work new and improved results for 210-214Fr, produced by α-decay of the primary reaction products 214-218Ac, were extracted. The results are discussed and compared to previously published data.
