Abstract：
Through measuring high-fold prompt γ-ray coincidence events of the spontaneous fission of ²⁵²Cf with the Gammasphere detector array, rotational bands in neutron-rich ⁹⁸Sr nucleus have been investigated. A deformed K=3 band built on 1838 keV level has been confirmed and extended. Another deformed K=6 band based on 2535 keV level has been established. Both bands originate most probably from the ν_9/2[404]⊙ν_3/2[411]two-quasiparticle configuration with Ω= |Ω₁－Ω₂|和Ω= |Ω₁+Ω₂|, respectively. Based on the delay-coincidence measurements, the half-lives for the K=3 and K=6 band head levels has bee obtained to be 13±3ns and 4.5±1.0ns, respectively.
