Theoretical evaluation of decay mode of ${}^{229m}\mathrm{Th}$ in solid samples

Ryotaro Masuda, Tomoya Naito, Masashi Kaneko +4

The excitation energy of ${}^{229m}\mathrm{Th}$ is extremely low at $8.4\mathrm{eV}$; thus, this isotope exhibits changes in its decay modes depending on the chemical stat…
