中子发射反应产生长寿命放射性的研究
Investigation of long lived activity produced due to neutron emitting reactions
摘要：
本文对中子发射实验产生的长寿命γ放射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的最基本特征之一。为此目的进行了几次实验。通常，使用在屈服截面中具有急剧曲率变化的实验。中子发射实验就是其中之一。在全球范围内，像$^7Li(p,n)$、$^{13}C(p,n)$、$^{19}F(p,n)$、$^{27}Al(p,n)$等反应被用来用加速器端电压校准束流能量。来自这些实验的中子可以与周围的元素相互作用。这些与中子的相互作用会产生长寿命的伽马活动，这可能会干扰未来的测量。本研究是在考虑到萨哈核物理研究所新的实验核天体物理研究设施的情况下进行的。这是一个3MV的串联低能量高电流机器。
英文摘要：
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.
