States in doubly odd 218Fr have been studied using in-beam spectroscopy α-γ-γ coincidence techniques mainly through the 209Bi(18O, 2αn) reaction at 94 MeV bombarding energy, using the 8π GASP-ISIS spectrometer at Legnaro. 218Fr shows a band structure, with interleaved states of alternating parities connected by enhanced E1 transitions. Tentative spin assignment and the relation between the structure of 218Fr and its isotone 220Ac is discussed.
