Improved limit on the effective electron neutrino mass with the ECHo-1k experiment
Fabienne Adam, Felix Ahrens, Luis E. Ardila Perez +56
The effective electron neutrino mass can be determined by analyzing the endpoint region of the Ho electron capture spectrum, provided a measurement with high energy resolut…

Single ion spectroscopy of four metastable state clear-out transitions in Yb II: isotope shifts and hyperfine structure
N. A. Diepeveen, C. Robalo Pereira, M. Mazzanti +5
We present spectroscopic data for four metastable state clear-out transitions between 399 nm and 412 nm for all even long-lived isotopes of Yb as well as their hyperfine struct…

Alignment and Optimisation of Optical Tweezers on Trapped Ions
M. Mazzanti, C. Robalo Pereira, N. A. Diepeveen +7
This paper presents a routine to align an optical tweezer on a single trapped ion and use the ion as a probe to characterize the tweezer. We find a smallest tweezer waist of $2.3(2…
