Excited states in 187Re populated by inelastic scattering of a 500 MeV 82Se beam have been studied by means of in-beam -ray spectroscopy. Levels built on the 5/2+ and 9/2- one-quasiparticle states were measured up to and (21/2-), respectively. In addition, several new levels including an isomer at 1682 keV with a half-life of 114(23) ns have been found. Quasiparticle configurations of the levels and the transition rates are discussed.
