Raman Transitions in Collinear Laser Spectroscopy for High-Precision Frequency Measurements
Julien Spahn, Hendrik Bodnar, Kristian König +2
We demonstrate stimulated Raman spectroscopy on dipole-forbidden fine-structure transitions in a fast ion beam. It is applied to the c…
Magnetic Dipole Hyperfine Constants of 15 Energy Levels in Tm II Determined by Collinear Laser Fluorescence Spectroscopy
Hendrik Bodnar, Kristian König, Wilfried Nörtershäuser
We present measurements of the hyperfine structure, transition frequencies and relative intensities in 14 lines of 169Tm+ ions starting from the $4f^{13}({}^2\!F^o_{7/2})6s_{1/2} (…
Nuclear Charge Radii of Sr Isotopes: Reevaluation based on Transition Frequency Measurements in the manifold in Sr
J. Palmes, K. König, B. K. Sahoo +10
High-precision quasi-simultaneous collinear and anticollinear laser spectroscopy was performed on the (D1), $5s\,^2S_{1/2}\rightarrow 5p\,^…
Demonstration of a Raman Velocity Filter in Collinear Laser Spectroscopy: Towards Applications for sub-ppm High-Voltage Measurements
Julien Spahn, Hendrik Bodnar, Kristian König +1
Raman transitions have a wide range of applications in atomic physics and have recently been proposed as a means for improving high-precision high-voltage measurements. Here, we pr…
