SPONTANEOUS NUCLEAR FISSION (in Russian)
The history of the early work on spontaneous fission in Kurchatov's laboratory is related. Further, results are reviewed on the systematics of spontaneously fissioning nuclides such as the well-known plots of hahf-life vs. Z/sup 2//A for even-even nuclei, and of half-life vs. neutron number. Mass distributions of fission fragments are given for U/sup 238/, Cm/sup 242/ and Cf/ sup 252/. The theory of spontaneous fission is re viewed from the point of view of a deformable liquid drop. Spontaneous fission applications in astrophysics and geophysics are given. The Cf/sup 254/ spontaneous fission half-life in supernovae is discussed, as is the presence of fission produced xenon in old rare- earth minerals. A discussion of transuranic elements is given, in which it is pointed out that spontaneous fission of very heavy elements is responsible for the limit of the atomic table. Spontaneous fission competes successfully with other modes of decay and makes production of very heavy elements difficult. (TTT)
