Hyperdeformed States in the Third Minimum of the Fission Potential

Research output: Contribution to journalArticle


The fission probability and the angular distribution of the associated fission fragments have been measured for the U-235(d,pf)U-236 reaction slightly above the top of the inner fission barrier with the aim of disclosing new hyperdeformed states lying in the third minimum of the fission potential. The results are analyzed together with the data obtained from the literature for U-234. The experimental resonances are interpreted as being rotational bands with rotational parameters of (h) over bar/2 Theta = 1.6 +/- 0.6 and 1.8 +/- 0.8 keV for U-234 and U-236 respectively. The K = 1, 2 and 4 values of the resonances suggest that these rotational bands are built on some higher-lying excited states in the third minimum of the potential well.
