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

Ternary fission of Cf-252 was studied at Gammasphere using eight DeltaE x 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 gamma transition from the first 2(+) excited state in Be-10 was found and the population probability ratio N(2(+))/N(0(+)) = 0.160 +/- 0.025 was estimated. No evidence was found for 3368-keV gamma 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. (C) 2004 MAIK "Nauka/Interperiodica".
