n＋^46-50,natTi全套中子数据评价

Evaluation of Complete Set of Neutron Data for n+～(46━50), ～(nat)Ti

在入射中子能量为10-5eV—20MeV的范围内,对n+46—50,natTi的全套数据进行了评价。首先,在10-5eV—0.3MeV的能区,选取了合适的共振参数来描述共振,并且做好了平滑区与共振区的连接。同时,详细分析了20MeV以下n+46—50,natTi的各个反应道测量截面以及出射中子双微分截面谱、能谱的实验数据。根据对实验数据的分析并且结合理论模型的计算结果,完成了对n+46—50,natTi的全套中子数据评价。所有的评价结果都分别与实验数据、JENDL-3.3和JEFF-3.1的评价数据进行了比较。

The complete neutron data of n＋^46—50, natTi, including cross sections of all reactions, angular distributions, double differential cross sections between 10^-5 eV—20 MeV, are evaluated by analyzing the experimental data and modifying theoretical results. And resonance parameters of mutilevel Breit-Wigner, which are offered in JEDNL3.3, are adopted into the new evaluated data sets. Meanwhile, all of evaluated values have been compared with existing experimental values and other evaluated results from JENDL-3.3 and JEFF-3.1.
