摘要
Dynamical calculations based on the four-dimensional stochastic Langevin approach are extended to the description of fragment isotopic distributions in fission at moderate-to-high excitation energy. Benefiting from previous theoretical work on charge-asymmetry relaxation times, and existing experimental charge-dispersion curves from low-energy fission, charge fluctuations are introduced at the scission point in an effective way. Comparison with recent suited measurements shows a good description over the full fragment production. The development proposed in this work can easily be implemented in other codes used in the field.
