(186g)Re is a β-/γ emitter of great interest for nuclear medicine. It has shown successful results on bone metastases palliation and has similar chemical properties as (99m)Tc, the most commonly used imaging agent. (186g)Re is routinely produced using rhenium target in nuclear reactor. Higher specific activity could be obtained using accelerators. In this paper, production cross section values are presented for the (nat)W(d,x)(186g)Re reaction up to 34MeV, using the stacked-foils method and gamma spectrometry. From this data set, the thick target production yield of (186g)Re is determined and compared with the validated values of the IAEA and also with the proton route. The production cross sections of the (nat)W(d,x)(183,182g,184m,184g,181)Re and (nat)W(d,x)(187)W reactions have also been determined. A good agreement is found with the literature. Our data are compared with the version 1.6 (December 2013) of the TALYS code which shows discrepancies both on the shape and on the amplitude for these deuteron induced reactions.
(186g)铼是核医学中备受关注的一种β-/γ发射体。它在缓解骨转移方面已取得成功结果,并且具有与最常用的成像剂(99m)锝相似的化学性质。(186g)铼通常在核反应堆中使用铼靶生产。使用加速器可以获得更高的比活度。在本文中,采用叠层箔法和γ能谱法给出了(天然)钨(d,x)(186g)铼反应在高达34MeV时的产额截面值。根据该数据集,确定了(186g)铼的厚靶产额,并与国际原子能机构的验证值以及质子途径进行了比较。还确定了(天然)钨(d,x)(183、182g、184m、184g、181)铼和(天然)钨(d,x)(187)钨反应的产额截面。与文献结果吻合良好。将我们的数据与TALYS代码1.6版(2013年12月)进行了比较,结果表明这些氘核诱导反应在形状和幅度上均存在差异。
