First experimental isotopic mapping of the fission “γ-bump” and its connection to the Pygmy dipole resonance

Nuclear fission produces two excited fragments which fast fly apart. Their properties at scission depend on the dynamics of fission, and rule their return to equilibrium. The present work addresses the excess of γ-rays with energies between 3 and 8 MeV emitted during the fragment de-excitation, reve...
