Abstract

Relative fission yields of ten nuclides produced by proton-induced fission of natural uranium and ${\mathrm{U}}^{235}$ were determined at several proton energies in the range 12 to 20 Mev. The expected trend toward symmetric fission at increased energies is observed. A statistical relation is used to correlate this shift in fission symmetry with the excitation energy of the compound nucleus.
