New data on the ternary fission of 252 Cf from the Gammasphere facility

Ternary fission of 252 Cf was studied at Gammasphere using eight Δ E × E particle telescopes. Helium, beryllium, boron, and carbon light charged particles (LCPs) emitted with kinetic energy more than 9, 21, 26, and 32 MeV, respectively, were identified. The 3368-keV γ transition from the first 2 + excited state in 10 Be was found and the population probability ratio N (2 + )/ N (0 + ) = 0.160 ± 0.025 was estimated. No evidence was found for 3368-keV γ rays emitted from a triple molecular state. For the first time, charge distributions are obtained for ternary fission fragments emitted with helium, beryllium, and carbon LCPs.
