Concepts for direct frequency-comb spectroscopy of Th and an internal-conversion-based solid-state nuclear clock
Lars von der Wense, Chuankun Zhang
A new concept for narrow-band direct nuclear laser spectroscopy of Th is proposed, using a single comb mode of a vacuum ultraviolet frequency comb generated from th…
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…
Towards a 229Th-based nuclear clock
Lars von der Wense, Benedict Seiferle, Peter G. Thirolf
An overview over the current status of the development of a nuclear clock based on the state of lowest known nuclear excitation energy in Th is presented. The text is espec…
Direct detection of the 229Th nuclear clock transition
Lars von der Wense, Benedict Seiferle, Mustapha Laatiaoui +9
Today's most precise time and frequency measurements are performed with optical atomic clocks. However, it has been proposed that they could potentially be outperformed by a nuclea…
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…
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…
Towards a direct transition energy measurement of the lowest nuclear excitation in 229Th
L. v. d. Wense, P. G. Thirolf, D. Kalb +1
The isomeric first excited state of the isotope 229Th exhibits the lowest nuclear excitation energy in the whole landscape of known atomic nuclei. For a long time this energy was r…
