Abstract
The191Bim,g →187T1 →183Au a-decay chain has been studied using mass — separated sources. The a — branching ratios have been measured. Out of the reduced a — decay widths, it is clear that the πs1/2 — πS1/2 and πh9/2 → πh9/2 transitions are not hindered although they involve strong shape changes.
