Comparative study of ¹⁵⁵Tb production via ¹⁵⁵Dy precursor with p, d and α beams on natural targets for medical applications

Three different reactions with the use of natural targets are investigated to produce ¹⁵⁵Tb for medical applications from the decay of its precursor ¹⁵⁵Dy. The TALYS code has been exploited to optimize the cross section description and to improve the agreement with the full set of available data. The study is completed by a theoretical model for the two radio-chemical separations: optimal solutions are presented for the production of high quality ¹⁵⁵Tb samples, guaranteed by the absence of the main contaminant, ¹⁵⁶Tb.
