States in doubly odd Fr216 have been studied using in-beam ±, and e- spectroscopy techniques through the Pb208(11B3n) fusion-evaporation reaction. Fr216 shows a band structure with interleaved states of alternating parities connected by enhanced B(E1) transitions. It represents the lowest-mass corner of the region (Z87,N129) in which this phenomenon is observed.
