On the production of 52gMn by deuteron irradiation on natural chromium and its radionuclidic purity

The positron emitter 52gMn is used for the Positron Emission Tomography - PET imaging.In this work we investigate the nuclear reactions for production of 52gMn and 54Mn induced by deuteron beams on natural chromium targets at energies up to Ed = 28 MeV using the stacked-foils activation technique. We calculate the thick target yields for 52gMn and for the radionuclidic impurity 54Mn, and we compare the radionuclidic purity of 52gMn with that achievable in proton activation of Cr. The cross-sections of the reactions natCr(d,pxn)51Cr and natCr(d,x)48V are also presented.
