论文摘要
在激子模型的背景下，考虑了平衡前反应机制。研究了对单粒子一孔状态密度的修改，可以解释为集体增强。通过模拟Lawrence Livermore国家实验室（LLNL）脉冲脉冲中子裂口光谱来确定集体增强的大小。集体增强的影响在高度变形的Actinide（239-PU）的背景下进行了探索。这种增强的结果是在现代核反应代码中经常使用的扭曲波生近似中的虚拟水平去除。
The pre-equilibrium reaction mechanism is considered in the context of the exciton model. A modification to the one-particle one-hole state density is studied which can be interpreted as a collective enhancement. The magnitude of the collective enhancement is set by simulating the Lawrence Livermore National Laboratory (LLNL) pulsed-spheres neutron-leakage spectra. The impact of the collective enhancement is explored in the context of the highly deformed actinide, 239-Pu. A consequence of this enhancement is the removal of fictitious levels in the Distorted-Wave Born Approximation often used in modern nuclear reaction codes.
