在回旋加速器上用$α$束从$^{nat}$ V靶生产高纯度$^{52g}$ Mn
Production of high purity $^{52g}$Mn from $^{nat}$V targets with $α$-beams at cyclotrons
摘要：
放射性同位素$^{52g}$ Mn对于多模态成像特别有用。使用最先进的核反应代码，我们研究了替代核反应路线$^{nat}$ V（$α$，x）$^{52g}$ Mn与基于使用铬靶的标准生产路线的比较。评价了$^{52g}$ Mn和污染物的积分产率。本研究的主要结果是，预计主要污染物同位素$^{54}$ Mn的产量低于$^{nat}$ Cr。该研究还揭示了一个大的传播的横截面数据集，并指出需要更精确的测量反应$^{nat}$ V（$α$，x）$^{52g}$ Mn以及需要一个更准确的理论描述。
英文摘要：
Radioisotope $^{52g}$Mn is of special interest for multimodal imaging. Using state-of-art nuclear reaction codes, we study the alternative nuclear reaction route $^{nat}$V($α$,x)$^{52g}$Mn in comparison with the standard production routes based upon the use of chromium targets. The integral yields of $^{52g}$Mn and contaminants have been evaluated. The main outcome of this investigation is that the production of the main contaminant isotope $^{54}$Mn is expected to be lower than with $^{nat}$Cr. The study also reveals a large spread in the cross-section data set and points out the need of more precise measurements of the reaction $^{nat}$V($α$,x)$^{52g}$Mn as well as the need of a more accurate theoretical description.
