Isomer ratios in fission fragments at high excitation

This is the authors' abstract. We don't add key points for this paper.

Isomer ratios in antimony and bromine fission fragments have been measured in the ( 12 C+ 209 Bi), ( alpha + 204 Pb) and ( 12 C+ 196 Pt) reactions, The values of the isomer ratios and their variation with energy are in accordance with the fragment angular momenta predicted by the Fermi gas model for the fissioning nucleus.
