Abstract

The energy and mass distributions and their correlations have been studied for the spontaneous fission of ²⁴²Pu and ²⁴⁴Pu and for the thermal-neutron induced fission of ²⁴¹Pu. A comparison of the ²⁴²Pu(s.f.) and the ²⁴¹Pu(n_th, f) results shows a narrower mass distribution, a much higher peak yield and a more pronounced fine structure for the spontaneous fission than for the neutron induced fission. The average total kinetic energy is higher for ²⁴²Pu(s.f.) than for ²⁴¹Pu(n_th, f), and also the energy-mass correlations behave differently in both cases. The ²⁴⁴Pu(s.f.) data are very similar to these for ²⁴²Pu(s.f.). All these results are discussed and interpreted in the frame of the scission point model of Wilkins et al.
