Improved ionization potential of calcium using frequency-comb based Rydberg spectroscopy
Chanhyun Pak, Matthew J. Schlitters, Scott D. Bergeson
We report new frequency-comb-based measurements of Ca Rydberg energy levels. Counter-propagating laser beams at 390 nm and 423 nm excite Ca atoms from the $4s^2~^1\mbox{S}_0$ groun…
Ion friction at small values of the Coulomb logarithm
Tucker Sprenkle, Adam Dodson, Quinton McKnight +4
Transport properties of high-energy-density plasmas are influenced by the ion collision rate. Traditionally, this rate involves the Coulomb logarithm, . Typical values of $\l…
Comment on "Laser cooling of Yb for isotope separation and precision hyperfine spectroscopy"
Quinton McKnight, Adam Dodson, Tucker Sprenkle +2
We present measurements of the hyperfine splitting in the Yb-173 states that disagree significantly with those measured previously by Das…
On the use of NaI scintillation for high stability nuclear decay rate measurements
Scott D. Bergeson, Michael J. Ware, Jeremy Hawk
We demonstrate the linearity and stability of a gamma-ray scintillation detector comprised of a NaI(Tl) crystal and a scientific-grade CMOS camera. After calibration, this detector…
Measurement of the Yb I transition frequency at 399 nm using an optical frequency comb
Michaela Kleinert, M. E. Gold Dahl, Scott D. Bergeson
We determine the frequency of the Yb I transition at 399 nm using an optical frequency comb. Although this transition was measured previously using an optical trans…
Velocity distribution measurements in atomic beams generated using laser induced back-ablation
A. Denning, A. Booth, S. Lee +2
We present measurements of the velocity distribution of calcium atoms in an atomic beam generated using a dual-stage laser back-ablation apparatus. Distributions are measured using…
