Feasibility Study of Internal Conversion Electron Spectroscopy of ${}^{229m}$Th

Benedict Seiferle, Lars von der Wense, Peter G. Thirolf

With an expected energy of 7.8(5) eV, the isomeric first excited state in ${}^{229}$Th exhibits the lowest excitation energy of all known nuclei. Until today, a value for the excitat…
