Excited states in ' Bi were populated by the " %'(' F,6n) and ' Tm( Si,4n) reactions. The subsequent y-ray emission was studied using in-beam spectroscopic methods including excitation functions, y-ray angular distributions, y-y-t coincidence, conversion electron, and pulsed-beam-y timing measurements.Three isomeric states were located in '9~Bi[ J,tq2, E]: [( 2 ), 32+2 ns, 888 keV];[( 2' ), 80+10 ns, 2196 keV]; and [( '2 ), 750250 ns, 2311+5keV]. The structure of the observed states is interpreted within the shell-model framework. Systematic features of excited state energies and transition rates in the odd-A bismuth isotopes are discussed. A comparison of intruder states analogous to those in odd-A antimony nuclei of the Z =50 transition region is made.
