Abstract: The high-spin states in 198Bi have been studied with the 187Re(16O,5n)198Bi reaction at 16O energies between 85 and 105 MeV.In-beam measurements of γ-ray excitation functions γ-γ-t coincidences and γ-ray angular distributions were carried out with 6 BGO(AC)HPGe detectors and an intrinsic Ge planar detector.A level scheme of 198Bi with 26 γ-rays was established for the first time,and an 15+ isomer was determined with t1/2=8.0±3.6ns.Based on the known level systematics in 200—206Bi,the level structure in 198Bi was qualitatively interpreted.
