Abstract

Radioisotope ^52gMn is of special interest for multimodal imaging. Using state-of-art nuclear reaction codes, we study the alternative nuclear reaction route ^natV($\alpha$,x)^52gMn in comparison with the standard production routes based upon the use of chromium targets. The integral yields of ^52gMn and contaminants have been evaluated. The main outcome of this investigation is that the ^52gMn yield of the new production route compares favorably with respect to the standard ^natCr one, and the contamination due to ⁵⁴Mn is expected to be significantly lower. 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 ^natV($\alpha$,x)^52gMn as well as the need of more refined models in nuclear reaction codes such as Talys, Empire, and Fluka.

摘要

放射性同位素^52g Mn 对多模态成像特别感兴趣。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($\alpha$,x) ^52g Mn，与基于使用铬靶材的标准生产路线相比。已经评估了^52g Mn 和污染物的积分产量。这项调查的主要结果是，新生产路线的^52g Mn 产量优于标准^nat Cr 1，预计^{54 Mn 造成的污染会显着降低。}该研究还揭示了横截面数据集中的较大分布，并指出需要更精确地测量反应^nat V($\alpha$,x) ^52g Mn 以及在 Talys、Empire 和 Fluka 等核反应代码中需要更精细的模型。
