Decoupling of radionuclide production cumulative cross-sections and TTY: Application to the process natDy(d, x)155Ho → 155Dy → 155Tb

Nuclear reaction cross-sections are sometimes presented as cumulative, in the sense that not all production is due to direct reactions, but the decay of a co-produced isomeric state or radioactive father contributes to the total yield of the reaction. In this paper, we discuss one of the scenarios that occur more frequently. Moreover, the results are employed to discuss one of the production routes of the medically relevant 155Tb.
