摘要：

High spin states in 74Kr were investigated in the reaction Ca-40(Ca-40,alpha-2p)74Kr at 125 and 140 MeV. A new decay scheme was established up to probable spin I = 20. The rotational structure was found to be similar to 76Kr, showing a double alignment in the ground-state band and sidebands with constant moments of inertia. Measured lifetimes using the Doppler-shift attenuation method indicate very collective E2 transitions in the ground-state band.
