Abstract High spin states of126Ba have been populated via the116Sn (13C, 3n) reaction and were investigated by inbeam gamma-ray spectroscopy. Partially NaJ (Tl)-BGO anti-compton shields were used. Two positive parity band crossings were established. The yrast band was observed up to a tentative 18+ level. The gamma-bands and two band structures of negative parity were found. In addition a tentative 3− state has been seen. Two-quasiparticle Routhians are constructed from the one-quasiparticle Routhians of the bands in the odd neighbouring isotopes and isotones and are compared to the ones observed in126Ba. This leads to ah 11/2 g 7/2-neutron structure of the strongly coupled negative parity bands and a two-quasiproton structure of the decoupled bands of negative parity. The branching and mixing ratios for the neutron bands are analyzed.
