Investigation of mass, charge and energy of 241Pu(nth, f) fragments with the Cosi-Fan-Tutte spectrometer

Abstract The mass, charge and energy distributions and their correlations have been studied for the fragments from thermal neutron-induced fission of 241 Pu, using the fission-fragment spectrometer Cosi-Fan-Tutte. The mass and charge distributions obtained agree with the corresponding radiochemical data. A proton even-odd effect of (10 ± 1.5)% on the nuclear-charge yield and 0.4 ± 0.2 MeV on the total kinetic energy has been determined. A fission-mode analysis on the nuclear-charge distribution has been performed.
