Abstract

Beams of 18-MeV $α$ particles and 70-MeV ${}^{16}O$ were used for $E 3$ Coulomb excitation of the weak-coupling $3^{-} | h_{\frac{9}{2}} 〉$ septuplet $J^{π} = {\frac{3}{2}}^{+}, \dots, \frac{15}{2^{+}}$ at 2.6 MeV in ${}^{209}{Bi}$ . A complete decay scheme was obtained and short lifetimes were determined from observed Doppler effects. We deduce several absolute transition probabilities for both excitation and decay involving the multiplet and low-lying single-particle states.
