Measurement Methodic of the Cross-Sections, Angular and Mass Distributions of the Debris at Electrofission of Heavy Nuclei in the Region of Giant Resonance
Abstract
A methodic is proposed to obtain cross-sections of electrofission of heavy nuclei in the energy region of giant resonance using the experimental measurements of the ratio of the photofission yield to the electrofission cross-section. Fission fragments are registered using glass cover and mailar films which are insensitive to charged background accompanying the fragments. A method has been proposed for cleaning the electron beam from gamma-background as well as the method of angular and mass distribution measurement of fission fragments.
