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…

Splitting Isotope Shift in the $1 s 2 p^{3} P_{0, 1, 2}$ Fine-Structure Triplet in $^{12, 13, 14}$ C $^{4 +}$ : Experiment and Theory

Patrick Müller, Kristian König, Emily Burbach +6

We report measurements and theoretical calculations of the fine-structure splittings in all three $1 s 2 s^{3} S_{1} \to 1 s 2 p^{3} P_{0, 1, 2}$ transitions in the heliumlike syst…
