Gamma-ray spectra produced in carbon, nitrogen, oxygen, sodium, aluminium, silicon, chlorine, calcium, chromium, iron, nickel, copper, zinc, and lead by 14 MeV tagged neutrons have been collected with NaI(Tl) detectors of the EURITRACK system, which low-energy threshold has been reduced to 0.6 MeV to detect gamma rays of major elements like iron. The spectra have been compared with Monte Carlo simulations to check the tabulated gamma-ray production data. A quantitative approach to subtract the scattered neutron background is also reported.
利用EURITRACK系统的碘化钠（铊）探测器收集了14兆电子伏特标记中子在碳、氮、氧、钠、铝、硅、氯、钙、铬、铁、镍、铜、锌和铅中产生的伽马射线能谱，该系统的低能阈值已降至0.6兆电子伏特，以探测铁等主要元素的伽马射线。已将这些能谱与蒙特卡罗模拟进行比较，以检验已列表的伽马射线产生数据。还报告了一种减去散射中子本底的定量方法。
