We measured, for the first time, the mass distribution of 240Pu 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 239Pu and isomeric fission of 240Pu. This indicates that the 240Pu system following the β-vibrational resonance descends into a fission valley which is identical to the fission valley of the 240Pu isomer and 239Pu(nth,f).
