[en] The most urgent problems of the role of statistical fluctuations in heavy ion collision and fission of compound nuclei are formulated. The classical dynamic calculations with fluctuating force based on the Langevin equation and one-body dissipation are presented

[en] Interpretation of nuclear deformations and resonance structure of the quadrupole strength function has been suggested within the semiclassical periodic orbit theory based on the Feynman's path integral representation for propagator

[en] A microscopical method is proposed to derive the diagonal and nondiagonal components of the inertia tensor for a dinuclear system. It is shown that the coupling of the radial and mass asymmetry modes is weak for almost symmetric configuration but it enhances significantly as the asymmetry increases

[en] The work is dedicated to the application of the noncompact group theory in nuclear spectroscopy. By the method of induced representations the principal series of representations of SL(3,IR) group is constructed. The results obtained are applied to the description of E 2-transition probabilities in even - even deformed nuclei (with mass number 150< A<194)

[en] The Fourth International school on nuclear physics was help on 29 Aug - 7 Sep, 1994 in Ukraine. The specialists discussed following subjects:liquid drop and the shell correction method; nuclear deformation energy and fission; nuclear structure at high spins, superdeformed states, structure of excited and exotic nuclei; nuclear fluid dynamics and large scale collective motion; order and chaos as they relate to the collective motion; quantum and interference phenomena in nuclear collisions; quasi-fission and multinucleon fragmentation effects; shell effects in non-nuclear systems; new nuclear facilities

[en] A brief analysis of time and energy compound-nucleus properties is given for the case of unresolved resonances. Then a realistic program of searching resonance and time compound-nucleus characteristics is presented basing on the statistical approach to evaluating the compound-nucleus cross sections, methods of obtaining compound-nucleus durations from known and proposed experiments and recently derived sum rules

[en] A semiclassical theory of collective vibrations, based on the linearized Vlasov equation, is reviewed, and reformulated in terms of angle-action variables. The relation between the expression obtained here for the zero-order polarization propagator and that derived previously by Brink et al. is discussed. A formulation of the theory useful for the study of collective vibrations in axially symmetric deformed systems is also discussed

[en] It is shown that an exponential decrease of inclusive energy spectra (accompanied by slight oscillations) with energy increase in high-energy nuclear reactions, independent of fragments, targets, projectiles and projectile energies, can be explained by a new phenomena of time resonances. Time resonances correspond to the formation of a few high-exited, long-living and non-exponentially decaying nuclear dots at the background of a spectator

[en] The conceptions of independent-particle and collective nuclear dynamics in the case of the simple oscillator shell model of a nucleus are proving so naturally related that just the same wave function of the excited nuclear state correspond to them. Our computations of the form factors of the giant resonance in the light nuclei, particularly in the nucleus ¹⁶ O, by ultrarelativistic electrons are leading to un definite results

[en] A highly excited compound nucleus decays mainly by emission of n,p and α and by nuclear fission. A detailed understanding of the competition between the different decay modes implies that the dependence of the evaporation probability on the deformation of the compound nucleus and its angular momentum is carefully studied. We present a new approach to the evaporation theory which is based on the Thomas-Fermi approximation. First numerical results show that the average transmission coefficient depends rather strongly on the nuclear deformation and rather weakly on the rotational frequency
