The fission probability of 232U has been measured using the 231Pa(3He,df) reaction with an energy resolution of 11 keV in the excitation energy region of E* = 4.0 - 6.4 MeV. A number of sub-barrier fission resonances has been observed for the first time in the excitation energy range below E* = 4.8 MeV and interpreted as rotational bands with a rotational parameter characteristic to a hyperdeformed nuclear shape (ℏ2/2Θ = 1.96 ± 0.11 keV). Besides, the fine structure of the transition states could also be resolved in the fission probability and proved to have a rotational structure with a rotational parameter characteristic to a superdeformed-like nuclear configuration (ℏ2/2Θ = 3.25 ± 0.17 keV).
