This work investigates the modeling of the fluctuations of fission observables (such as the neutrons and γ multiplicity, the average kinetic energy of fragments) in the resonance range. A formalism combining fission channels and fission modes gives a tractable methodology to study this longstanding issue. The present work explores the channel-mode formalism but includes also the effect of prefission γ. The case of 235U fission below 20 eV is studied.
