Ultrahigh-precision measurement of the $n = 2$ triplet P fine structure of atomic helium using frequency-offset separated oscillatory fields

K. Kato, T. D. G. Skinner, E. A. Hessels

For decades, improved theory and experiment of the $n = 2$ $^{3}$ P fine structure of helium have allowed for increasingly-precise tests of quantum electrodynamics, determinations of th…

Orientation-dependent hyperfine structure of polar molecules in a rare-gas matrix: a scheme for measuring the electron electric dipole moment

A. C. Vutha, M. Horbatsch, E. A. Hessels

Because molecules can have their orientation locked when embedded into a solid rare-gas matrix, their hyperfine structure is strongly perturbed relative to the freely rotating mole…

Systematic effects important to separated-oscillatory-field measurements of the $n$ $=$ $2$ Lamb shift in atomic hydrogen

A. Marsman, M. Horbatsch, Z. A. Corriveau +1

We evaluate a number of systematic effects that are important for an experimental microwave measurement of the $n$ $=$ $2$ S-to-P intervals in atomic hydrogen. The analysis is import…
