Abstract：
The high-spin states of ¹⁹⁸Bi have been studied via the reaction ¹⁸⁷Re(¹⁶O, 5n)¹⁹⁸Bi at ¹⁶O energies from 85-105MeV. 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 1 intrinsic Ge planar detector. A level scheme for ¹⁹⁸Bi with 26 γ-rays was established for the first time, including a 15⁺ isomer with a measured half-life of 8.0±3.6ns. Based on the known level structure systematics in ^200-206Bi, the level structure of ¹⁹⁸Bi was qualitatively interpreted by using semi-empirical methods.
