For the fist time the non- monotonous dependence of the penetration probability through the fission barrier on the frequency of modulating force was found. For the first time it was found that the resonant enhancement of the penetration probability trough the fission barrier takes place at the frequency inversely proportional to the mean time of passing through the fission barrier in Kramers' diffusion theory/ The optimal shapes of rotating nuclei at the arbitrary values of the fissility parameter and angular velocity are investigated. It is found the sharp transition from the oblate to prolate spheroidal shapes with increase of angular moment. The value of critical angular moments by which the rotating nucleus looses its stability with respect to fission is calculated. It is shown that the axial asymmetry has a considerable influence on the moments of inertia and rotational spectra of nuclei, in particular, it defines the limits of the rotational spectra.
