摘      要：The ground-state bands of Cf248,250,252 have been established up to the 10+, 12+, and 10+ states, respectively, by in-beam γ-ray spectroscopy using neutron-transfer reactions with a 153-MeV O18 beam and a highly radioactive Cf target. The deexcitation γ rays in Cf248,250,252 were identified by taking coincidences with outgoing particles of O16−19 measured with Si ΔE−E detectors, and by selecting their kinetic energies. Moments of inertia of Cf248,250,252 were discussed in terms of the N=152 deformed shell gap.
