A VUV detection system for the direct photonic identification of the first excited isomeric state of ${}^{229}$Th

Benedict Seiferle, Lars von der Wense, Mustapha Laatiaoui +1

With an expected energy of 7.6(5) eV, ${}^{229}$Th possesses the lowest excited nuclear state in the landscape of all presently known nuclei. The energy corresponds to a wavelength o…
