The structure of /sup 215/Fr has been studied via the /sup 208/Pb (/sup 11/B, 4n..gamma..)/sup 215/Fr reaction at beam energies from 45 to 66 MeV. In-beam ..gamma..-ray spectroscopy techniques, including ..gamma..-ray excitation function, x-ray-..gamma.. coincidence, ..gamma..-..gamma.. coincidence, ..gamma..-ray angular distribution, and ..gamma..-ray linear polarization measurements were used to construct a level scheme up to a spin value J = (41/2) at an excitation energy of 3405 keV. Definite parity assignments were made up to the (39/2)/sup -/ state. The structure of this nucleus is compared with that observed in the other N = 128 isotopes and predictions of shell model calculations.
