Excited states in 208 Fr have been identified using the 197 Au( 16 O, 5n) 208 Fr reaction and a variety of time-correlated γ-ray and conversion electron spectroscopic techniques. Transitions above and below a τ = 623(16) ns 10 − isomer are placed in the level scheme. This isomer is analogous to that observed in the odd-odd isotone 206 At for which additional spectroscopic information is also obtained, including a precise lifetime of τ = 1173(30) ns. The γ-rays assigned to 208 Fr are the same as the main transitions erroneously assigned to 209 Fr in previous work.
