Abstract
We measured, for the first time, the mass distribution of fission fragments following the β-vibrational resonance, whose level is formed on the second minimum of the double-humped fission barrier. The distribution shows an asymmetric mass distribution similar to the one observed for thermal neutron-induced fission of and isomeric fission of This indicates that the system following the β-vibrational resonance descends into a fission valley which is identical to the fission valley of the isomer and
