Abstract

The ground state rotational bands in233U and239Pu were investigated in (α, 3n) reactions. Conversion electrons were measured with an iron free orange spectrometer in order to suppress the background from fission. Levels up toI π=33/2+ of theK=5/2 band in233U andI π=31/2+ of theK=1/2 band in239Pu were identified ine −γ coincidence measurements. The level energies of both rotational bands can be well described up to the highest observed spins by a two-parameter angular velocity expansion. The electromagnetic properties of theK=1/2 band in239Pu are discussed.
