THEORY OF NUCLEAR FISSION. II. THE DEFORMATION OF THE FISSION FRAGMENTS (in German)
The total excitation energy E of both fragments (for the fission of U/ sup 2//sup 3//sup 5/ with thermal neutrons) was calculated with the help of the energy conservation principle-by use of the Fong mass formula for primary fission products-from the experimental data of the mean kinetic energy of the fragments. This energy possesses a sharp minimum for the case that one of the fragments lies in the vicinity of magic nuclei (N = 82, Z = 50). Under the assumption that the distribution of E on both fragments occurs in proportion to their masses, the deformation of the fragments was determined from E by means of the simple drop modelunder consideration of the dependence of the surface tension on the shell structure. The deformation parameter of a fragment shows, as a function of the neutron number of the nucleus considered, characteristic steep slope for the magic neutron numbers. (tr-auth)
