Ternary fission yields of 241Pu(nth,f) Original Research Article

Ternary events in the thermal neutron induced fission of 241Pu(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 30Mg 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 11Li, 14Be and 19C were found in neutron induced fission with yields of some 10−10 per fission.
