A Spectrometer for Investigation of Ternary Nuclear Fission

Abstract

A spectrometer for studying ternary nuclear fission on the basis of a double ionization chamber and a thin Cs(Tl) crystal is described. Four detector signals are digitized and stored in the computer memory. Digital signal processing provides data on the energies, masses, and emission angles of fragments and on the energy and type of light particles coinciding with them. The measured characteristics of the spectrometer allow for its successful use in studies of ternary fission with the emission of α particles, tritons, and protons, as well as in the search for exotic nuclear decays accompanied by the emission of charged mesons.
