On the rearrangement time of the fission reaction
arXiv:1004.1337
Abstract
The rearrangement time \Deltat of the fission reaction can be extracted from the full-width at half maximum (f.w.h.m.) of the isotopic distributions of fission fragments if this width is attributed to an uncertainty \DeltaN in the neutron-number N of the fragment; then the energy-time uncertainty relation leads to \Deltat = 0.17 yoctosecond.
