The positron emitter Mn is used for the Positron Emission Tomography - PET imaging.In this work we investigate the nuclear reactions for production of Mn and Mn induced by deuteron beams on natural chromium targets at energies up to E = 28 MeV using the stacked-foils activation technique. We calculate the thick target yields for Mn and for the radionuclidic impurity Mn, and we compare the radionuclidic purity of Mn with that achievable in proton activation of Cr. The cross-sections of the reactions Cr(d,pxn)Cr and Cr(d,x)V are also presented.
正电子发射体锰用于正电子发射断层扫描（PET）成像。在这项工作中，我们使用叠层箔活化技术研究了能量高达E = 28 MeV的氘核束在天然铬靶上产生锰-52和锰-54的核反应。我们计算了锰-52和放射性核素杂质锰-54的厚靶产额，并将锰-52的放射性核素纯度与铬质子活化所能达到的纯度进行了比较。还给出了反应Cr(d,pxn)Cr和Cr(d,x)V的截面。
