Abstract :
The γ decay of excited states built on the superdeformed shape isomer 240fPu was measured for the first time with an array of EUROBALL CLUSTER detectors in coincidence with delayed fission decays using the 238U(α,2n) reaction. The strongest γ transitions can be assigned to the out-of-band decays of three excited superdeformed rotational sequences: A Kπ=2− and Kπ=1−(2−) band with respective bandhead energies of 806.2 keV and 836.0 (846.8) keV decaying to the ground state band of 240fPu, and a Kπ=2(1) band at 1360.9 (1344) keV populating mainly the Kπ=2− (806.2 keV) band.
