Abstract：
Excited states of ⁸⁸Sr have been produced in the fusion evaporation reaction between ⁸²Se beam and ¹⁶O from a heavily oxidized Ba target and studied using the in-beam γspectroscopy tech- niques. Two high-spin level structures have been Observed and established up to 8.5MeV and 7.9MeV excitation energy with spin values of 13h and 12h, respectively. Based on the measure- ments of the DCO ratios and anisotropies of γ-rays, spin values of the excited states have been as- signed up to the highest levels observed. Possible coofgurations are discussed for the two high spin level structures.
