Production of high purity ${}^{52g}$Mn from ${}^{nat}$V targets with $\hat{I}\pm$-beams at cyclotrons

Abstract

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($\hat{I}\pm$,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($\hat{I}\pm$,x)${}^{52g}$Mn as well as the need of a more accurate theoretical description.
