Polar light charged particles accompanying spontaneous fission

Abstract

Simple model of emission of light charged polar particles accompanying fission of heavy nuclei is presented. We assume the emission from the whole surface of fragments after scission, taking into account the influence of the accompanying fragment. The initial energy and time of emission are treated phenomenologically. The motion of light particles and fission fragments are subsequently calculated in the framework of classical dynamics. We get a good agreement with experimental data if we assume a prompt emission. The possibility of the connection with giant resonances is discussed.
