Polarization-Dependent Disappearance of a Resonance Signal -- Indication for Optical Pumping in a Storage Ring?
W. Nörtershäuser, A. Surzhykov, R. Sánchez +10
We report on laser spectroscopic measurements on Li ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the $2s\,^3\!{S}_1\;(F…
Measuring the Variation in Nuclear Charge Radius of Xe Isotopes by EUV Spectroscopy of Highly-Charged Na-like Ions
R. Silwal, A. Lapierre, J. D. Gillaspy +8
The variation in mean-square nuclear charge radius of xenon isotopes was measured utilizing a new method based on extreme ultraviolet spectroscopy of highly charged Na-like ions. T…
Isotope Shifts in the 7s8s Transition of Francium: Measurements and Comparison to \textit{ab initio} Theory
M. R. Kalita, J. A. Behr, A. Gorelov +10
We observe the electric-dipole forbidden transition in the francium isotopes Fr and Fr using a two-photon excitation scheme. We collect the at…
Hyperfine anomalies in Fr: boundaries of the spherical single particle model
J. Zhang, M. Tandecki. R. Collister, S. Aubin +6
We have measured the hyperfine splitting of the state at the 100 ppm level in Fr isotopes (Fr) near the closed neutron shell ( = 126…
Test of Time Dilation Using Stored Li+ Ions as Clocks at Relativistic Speed
Benjamin Botermann, Dennis Bing, Christopher Geppert +14
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of beta = v/c = 0.338 in the storage ring ESR at Darmsta…
Commissioning of the Francium Trapping Facility at TRIUMF
M. Tandecki, J. Zhang, R. Collister +6
We report on the successful commissioning of the Francium Trapping Facility at TRIUMF. Large laser-cooled samples of francium are produced from a francium ion beam delivered by the…
