论文摘要
在本文中，由于中子排放实验，已经为长期存在的伽马活性进行了详细的研究。这些计算主要集中在用于能量校准目的的实验上。校准能量是任何加速器设施中最重要的特征之一。为此，已将一些实验用于此目的。通常，使用产量的横截面上具有急剧曲率变化的实验。中子发射实验就是其中之一。 $^7li（p，n）$，$^{13} c（p，n）$，$^{19} f（p，n）$，$^{27} al（p，n）$等全球反应。来自这些实验的中子可以与周围元素相互作用。这些与中子的相互作用会产生长期存在的伽马活性，这可能会干扰未来的测量。牢记了本研究的研究，萨哈核物理研究所的实验性核天体物理学研究（FRENA）的新设施。它是3MV Tandetron低能电流机器。
In this article, a detailed investigation has been done for the long lived gamma activity due to neutron emitting experiments. These calculations mainly focused on the experiments used for energy calibration purposes. Calibrated energy is one of the most essential features of any accelerator facility. Several experiments have been used for this purpose. Generally, experiments having sharp curvature change in cross section of yield are used. Neutron emitting experiments are one of such. Around the globe reactions like $^7Li(p,n)$, $^{13}C(p,n)$, $^{19}F(p,n)$, $^{27}Al(p,n)$ etc. are used to calibrate energy of the beam with accelerator terminal voltage. Neutrons coming from these experiments can interact with surrounding elements. These interactions with neutrons can create long lived gamma activity which may interfere with future measurements. The present study has been done keeping in mind the new Facility for Research in Experimental Nuclear Astrophysics (FRENA) at Saha Institute of Nuclear Physics. It is a 3MV tandetron low energy high current machine.
