Towards a precise determination of the excitation energy of the Thorium nuclear isomer using a magnetic bottle spectrometer
Benedict Seiferle, Lars von der Wense, Ines Amersdorffer +3
Th is the only known nucleus with an excited state that offers the possibility for a direct laser excitation using existing laser technology. Its excitation energy has been…
The extraction of 229Th3+ from a buffer-gas stopping cell
Lars von der Wense, Benedict Seiferle, Mustapha Laatiaoui +1
In the whole landscape of atomic nuclei, Th is currently the only known nucleus which could allow for the development of a nuclear-based frequency standard, as it possesses…
Feasibility Study of Internal Conversion Electron Spectroscopy of 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 Th exhibits the lowest excitation energy of all known nuclei. Until today, a value for the excitat…
Determination of the extraction efficiency for U source -recoil ions from the MLL buffer-gas stopping cell
Lars von der Wense, Benedict Seiferle, Mustapha Laatiaoui +1
Following the decay of U, Th recoil ions are shown to be extracted in a significant amount from the MLL buffer-gas stopping cell. The produced recoil ions and s…
A VUV detection system for the direct photonic identification of the first excited isomeric state of Th
Benedict Seiferle, Lars von der Wense, Mustapha Laatiaoui +1
With an expected energy of 7.6(5) eV, Th possesses the lowest excited nuclear state in the landscape of all presently known nuclei. The energy corresponds to a wavelength o…
