Optical clocks based on the Cf and Cf ions
S. G. Porsev, U. I. Safronova, M. S. Safronova +4
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly-charged ions (HCIs) made HCIs accessible for high resolution spectroscopy and precision…
Nobelium energy levels and hyperfine structure constants
S. G. Porsev, M. S. Safronova, U. I. Safronova +2
Advances in laser spectroscopy of superheavy () elements enabled determination of the nuclear moments of the heaviest nuclei, which requires high-precision atomic calculatio…
Clock-related properties of Lu+
S. G. Porsev, U. I. Safronova, M. S. Safronova
The singly-ionized lutetium has a number of fortuitous properties well suited for a design of an optical clock and corresponding applications. In this work, we study Lu+ properties…
High-precision measurements and theoretical calculations of indium excited-state polarizabilities
N. B. Vilas, B. -Y. Wang, P. M. Rupasinghe +4
We report measurements of the In and scalar and tensor polarizabilities using two-step diode laser spectroscopy in an atomic beam. The scalar polariza…
Ultracold anions for high-precision antihydrogen experiments
G. Cerchiari, A. Kellerbauer, M. S. Safronova +2
Experiments with antihydrogen () for a study of matter--antimatter symmetry and antimatter gravity require ultracold to reach ultimate pr…
Multipolar polarizabilities and hyperpolarizabilities in the Sr optical lattice clock
S. G. Porsev, M. S. Safronova, U. I. Safronova. +1
We address the problem of the lattice Stark shifts in the Sr clock caused by the multipolar and atom-field interactions and by the term nonlinear in lattice intensity and…
