耗散反应产物的电荷扩散与能量相干

Energy Coherence and Charge Diffusion in Dissipative Reactions

在输运理论的框架内研究了１９Ｆ＋５１Ｖ耗散反应中能量相干宽度随出射产物中质比Ｎ／Ｚ变化的关系，得到了反应系统已经达到电荷平衡的结论，提取了相应的电荷扩散系数。分析表明电荷扩散过程造成了的分布宽度随反应时间线性增大的现象。还探讨了各个同位素出射道的相关对激发函数振荡结构涨落幅度的作用。

In the framework of transport theory, the variation of coherence energy width 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 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.
