It has been known for many years that the first excited state of $^{229}\mathrm{Th}$ lies close to the ground state. Originally this energy was given as 0.1 keV; later, the authors reported a value of -1\ifmmode\pm\else\textpm\fi{}4 eV. In an attempt

In this paper, the authors point out that data from earlier experiments carried out to measure beta-strength functions for short-lived fission products can also be used to provide average beta- and gamma-decay energy values for these nuclides. In the
