摘要: Nuclear fission accompanied by long-range alpha particles has been investigated. Fission was induced irradiating a natural uranium target with 13.5 MeV deuterons. The energy and angular distributions are similar to those observed in spontaneous or thermal neutron fission. correlation angle between light fragments most probable value of\(\bar \vartheta _{l f - \alpha } = 82.1^\circ \pm 0.9^\circ \) dispersion (FWHM) of Δϑ=18.4°±1.2°. mean the distribution are\(\bar {\rm E}_\alpha 14.8 1.0 MeV\) ΔE=9.1±1.2 (FWHM), respectively. peak-to-valley ratio ternary fragment mass is found increase increasing energy. For near-symmetric division, strong broadening observed. results discussed frame multichannel-fission model.
