随机模型被用于分析3He+197Au，3He+208Pb和3He 186W反应测量的裂变激发函数。提取的鞍点前摩擦强度约为4×1021 s-1。揭示了能级密度参数的大小在约束核摩擦强度中的作用。计算表明，高激发条件能能显著增强裂变截面对核耗散的敏感性。
The stochastic approach to fission is employed to analyze measured fission excitation func-tions in the reactions 3He+197Au, 3He+208Pb and 3He+186W. A pre-saddle friction strength of about 4 × 1021 s-1 is extracted by comparing theoretical calculations with experimental data. The important role of level-density parameters in accurately determining the strength of nuclear friction is revealed. It is further shown that high-energy conditions can enhance the sensitivity of fission cross sections to nuclear dissipation.
