High-spin states in 200Hg have been investigated by in-beam -ray spectroscopy following the reaction 198Pt(9Be,3n). The -emission channel leading to 200Hg is strongly enhanced which may be explained by an incomplete fusion reaction with pre-equilibrium emission of the particle. The level scheme is extended to higher spins and new band crossings are observed. The band structures are compared to the lighter Hg isotopes with even mass number.
