Abstract：
In the framework of transport theory, the variation of coherence energy width Γ with neutron-charge ratio N/Z for the ¹⁹F+⁵¹V dissipative reaction is compre-hensively discussed. It can be concluded that the charge equilibrium is reached in the present colliding system. The charge diffusion coefficent is also extracted from the analysis The proportional relation between Γ distribution width and average interaction time is ascribed to the charge diffusion process. The effects of cross correlation between different isotopes on fluctuation amplitude are also discussed.
