ELECTROMICROSCOPIC INVESTIGATION OF URANIUM FISSION

Abstract

A new method of preparing electronmicroscopic specimens of high resolution (10A), based on the phenomenon of cathode sputtering of metals, has been developed. The interaction of the fission fragments of U-235 with the given specimens has been studied using an electron microscope of high resolution (down to 7A). It has been established that, in specimens with a grain size of less than 40A, the fission fragments form hollow canals with a diameter of from 20A to 200A, which are preserved for a long time. In crystalline specimens with a grain size of more than 100A the canals are not preserved but are 'self-heated' as a result of the collective reorganization of atoms. (Author)
