Isotope Shifts in Cadmium as a Sensitive Probe for Physics Beyond the Standard Model

Autor: Ohayon, B., Hofsäss, S., Padilla-Castillo, J. E., Wright, S. C., Meijer, G., Truppe, S., Gibble, K., Sahoo, B. K.

Isotope shifts (ISs) in atomic energy levels are sensitive probes of nuclear structure and new physics beyond the Standard Model. We present an analysis of the ISs of the cadmium atom (Cd I) and singly charged cadmium ion (Cd II). ISs of the 229 nm,

Advances in the accuracy, stability, and reliability of the PTB primary fountain clocks

Autor: Weyers, S., Gerginov, V., Kazda, M., Rahm, J., Lipphardt, B., Dobrev, G., Gibble, K.

Publikováno v: Metrologia 55, 789 (2018)

Improvements of the systematic uncertainty, frequency instability, and long-term reliability of the two caesium fountain primary frequency standards CSF1 and CSF2 at PTB (Physikalisch-Technische Bundesanstalt) are described. We have further investiga

Distributed cavity phase frequency shifts of the caesium fountain PTB-CSF2

Autor: Weyers, S., Gerginov, V., Nemitz, N., Li, R., Gibble, K.

Publikováno v: Metrologia 49, 82 (2012)

We evaluate the frequency error from distributed cavity phase in the caesium fountain clock PTB-CSF2 at the Physikalisch-Technische Bundesanstalt with a combination of frequency measurements and ab initio calculations. The associated uncertainty is 1
