Abstract

Independent fission yields and fragment kinetic energies in the very asymmetric (A=87−72) fission of 249Cf have been measured using the mass separator LOHENGRIN at the Institut Laue-Langevin in Grenoble. The mass yields were found to be up to a factor of 100 higher than predicted in the US ENDF-V file. A preliminary evaluation of the isotopic yields shows a strong increase of the proton odd-even effect from 7 % to 15 %. This can be explained by a decreasing excitation energy in this very asymmetric region.
