Abstract

The radionuclide ¹⁵²Tb, decaying by

β^{+}

emission and electron capture to ¹⁵²Gd with

17.8784(95) h, has been shown in its first-in-human use to be suitable for positron emission tomography (PET) imaging. As a member of the terbium theragnostic quartet, this radionuclide has potential applications in personalised cancer treatments. Sources of ¹⁵²Tb were produced by proton-induced spallation of a tantalum target followed by on-line mass separation at CERN-ISOLDE. The sources were delivered to ILL Grenoble, where gamma–gamma coincidence spectroscopy of excited states populated in ¹⁵²Gd following the decay was carried out using the Fission Product Prompt

-ray Spectrometer (FIPPS). Preliminary analysis has resulted in the identification of multiple previously unreported excited states in ¹⁵²Gd, thirteen of which are reported here at excitation energies up to 3746 keV. Angular correlation analysis has been used to provide initial spin and parity assignments to excited states. The result of the completed spectroscopy will be a revised gamma-ray and

dose to patients compared to the current expected values.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
