Abstract.

The α-decay fine structure of 214Ac, 215Ac and 216Ac has been studied using the α-γ-coincidence technique. The nuclei were produced by 209Bi( 12C, xn)221-xAc-reactions. Evaporation residues were separated in-flight from the primary beam using the velocity filter SHIP at GSI, Darmstadt. The separated nuclei were implanted into a position-sensitive 16-strip PIPS Si detector and their subsequent decays were measured. In these studies new and improved decay data for 214-216Ac were obtained.
