[en] The problem of an apparent inconsistency between the fission rates derived on the basis of Bohr-Wheeler's transition-state method and Kramers' dynamical model of nuclear fission, first pointed out by Strutinsky in 1973, is revisited. The study is based on studying the features of individual trajectories on the fission path. (authors)

[en] In their famous 1939 paper on the physics of nuclear fission, Niels Bohr and John Wheeler presented an eye-catching graph of the fission barrier energy for various nuclides. In this paper I develop a simplified approach to developing this graph which is both sensibly true to their analysis and appropriate for a student audience. (paper)

[en] It has been shown on the basis of a diffusion model for nuclear fission, that the fission width is time-dependent [GR 83]. only after a certain time, which depends essentially on the nuclear friction constant, the fission width approaches the value predicted by the Bohr-Wheeler formula. The authors solve time-dependent master-equations which describe the cascade de-excitation of the compound nucleus, including the transient behaviour of fission. They calculate the neutron and proton multiplicities as a function of the transient time. The comparison with experimental data should give an information on the value of the nuclear friction constant

[en] An outline of the history of fission is presented beginning 1934, when fission products were first produced by neutron-irradiation of uranium but were attributed to transuranium elements, till December 1938, when fission was discovered with radiochemical techniques and confirmed in the following weeks with physical methods.

[en] The recent observation that the empirical threshold for fission hindrance correlates with the ratio of the threshold temperature to the temperature dependent fission barrier height is interpreted in terms of Bohr-Wheeler theory. A total fission delay of (2--4) times 10 sup -2--- s is deduced from the empirical value of this ratio
