| 摘 要： | 利用中国原子能科学研究院HI-13串列加速器上的多探测器快中子飞行时间谱仪， 测量了38个不同入射质子能量点下15N（p, n)15O反应0°角方向的激发函数。 测量数据用蒙特卡罗方法进行了模拟， 以进行中子注量衰减和入射窗厚度的不确定度修正。 实验在入射质子能量位于6.029—8.056 MeV之间时发现了3个共振峰， 这一点与DROSG 2000评价数据及PTB数据相符合， 但三家的截面数值存在差异， 对这些差异需要作进一步深入探讨。 The excitation function of 15N（p, n)15O reaction at 0 degree was measured at 38 energy points using the fast neutron Time of Flight (TOF) spectrometer at the HI 13 Tandem Accelerator in the China Institute of Atomic Energy（CIAE）. The measured data were analyzed by Monte Carlo simulation for the corrections of neutron flux attenuation and uncertainty of the thickness of the entrance foil. Three resonance peaks were observed in this experiment in the energy range from 6.029 to 8.056 MeV，which is comparable with the DROSG 2000 evaluated data and the PTB data. However，more experimental studies are needed since the cross sections deviate with each other.
