Abstract：
High-spin states in ⁷⁹Kr were studied via the fusion evaporation reaction ⁵⁵Mn(³⁰Si, apn) at 130MeV. Prompt γγγ-charged particle coincidences were made using the GASP array in conjunction with the ΔE-E Si(Au) charged particle ball. Nine new states were found, along with 10 new transitions in the K=5-/2 band. The favored (a=+1/2) and unfavored (a=－1/2) signature sequences were extended up to states of (37-/2)8992 keV and (59－/2)20132 keV, respectively. A cranked shell-model analysis has been made to discuss the experimental results.
