Extended Data Fig. 1: High-purity germanium detector spectra.
From: Observation of the radiative decay of the 229Th nuclear clock isomer
Single γ spectra recorded with the HPGe detector for a typical implantation at A = 229 (a) and A = 230 (b). The main peaks in the spectrum are marked with the β-decaying isotope and the energy. In this study, new γ lines in the decay of 229Ra were identified, these tentative assignments are indicated with an asterisk. The inset shows the high-energy part of the spectrum with smaller peaks.
