Excitation functions for the production of 154Dy in proton irradiated Ta (a), Pb (b), and W (c) targets. Solid lines: theoretical values obtained with INCL + + and ABLA 07 codes; filled dots: experimental values using t1/2 = (1.40 ± 0.08) My; open squares: experimental values using t1/2 = (3.0 ± 1.5) My.
