Charged particle induced ternary fission

Description
Ternary fission has been investigated by irradiating a natural uranium target with 13.5 MeV deuterons. The energy and angular distributions of ternary alpha particles do not differ from those observed in spontaneous or thermal neutron induced fission. The angle between alpha particles and light fragments has a most probable value of anti θlf-α = 82.10 ± 0.60 with a dispersion (FWHM) of Δθ = 18.40 ± 1.20. The corresponding values of the energy distribution are anti E α = (14.8 ± 0.5) MeV and ΔE(FWHM) = (9.1 ± 1.1) MeV. The peak-to-valley ratio of the ternary fission fragment mass distribution is found to increase with increasing alpha energy. For near-symmetric mass division a strong broadening of the angular distribution is observed. (orig.)
