Ternary fission yields of 241Pu(nth,f)

Abstract Ternary events in the thermal neutron induced fission of 241 Pu(n,f) were studied with the recoil separator LOHENGRIN at the high-flux reactor of the Institut Laue Langevin in Grenoble. Yields and energy distributions could be determined for most isotopes of the elements hydrogen to oxygen. Also several heavier nuclei up to 30 Mg could be observed. Yields were measured for 42 isotopes, for further 17 isotopes upper limits could be deduced. For the first time the halo nuclei 11 Li, 14 Be and 19 C were found in neutron induced fission with yields of some 10 −10 per fission.
