Measuring decay of praseodymium isotopes activated by a clinical LINAC

Abstract

The decay of [Formula: see text]Pr produced by activation with a clinical LINAC was investigated. The sample was counted by a HPGe detector with 40% relative efficiency. Transitions created by beta decay of [Formula: see text]Pr were observed and corresponding energies lines and relative transition strengths were measured. In addition, half-life of [Formula: see text]Pr was obtained at 3.38 ± 0.06 min. The experimental results fitted nicely to the existing energy levels scheme of [Formula: see text]Pr. Notably, all results for transition energies are more accurate than the literature values, while the half-life and transition strengths showed accuracy similar to that of the literature.
