96Zr(n,2n)95Zr、176Hf(n,2n)175Hf实验测量数据较分散,且在某些能区分歧较大。近几年增添了新的实验数据,本工作收集了这两个反应道的实验数据,并进行一定的修正、分析与评价,给出较理想的激发函数曲线。96Zr(n,2n)95Zr实验数据大多集中在14 MeV附近,且分歧较小。8~12 MeV能区仅有两家实验数据,其中8~10 MeV两家测量值较为接近,而入射中子能量超过10 MeV时,分歧较大。本工作采用核反应模型程序TALYS进行计算,以8~10 MeV和14 MeV附近的测量数据为根据调参,得到8~20 MeV能区的激发函数曲线,如图1所示。对于176Hf(n,2n)175Hf,集中
96Zr (n, 2n) 95Zr, 176Hf (n, 2n) 175Hf The experimental data are more scattered and have more divergence in some energy regions. In recent years, new experimental data have been added. In this work, the experimental data of the two reaction channels are collected, and some corrections, analyzes and evaluations are made, and the ideal excitation function curve is given. 96Zr (n, 2n) 95Zr experimental data are mostly concentrated in the vicinity of 14 MeV, and the differences are small. There are only two experimental data in the 8 ~ 12 MeV energy region, of which the 8 ~ 10 MeV measurements are close to each other, while the incident neutron energy exceeds 10 MeV, the differences are large. In this work, the nuclear reaction model program TALYS was used to calculate the excited function curve of 8-20 MeV energy region based on the measured data of 8-10 MeV and 14 MeV, as shown in Fig.1. For 176Hf (n, 2n) 175Hf, concentrate
