Improved access to the fine-structure constant with the simplest atomic systems

Atomic Physics 2020-06-26 v1 Quantum Physics

Abstract

A means to extract the fine-structure constant α\alpha from precision spectroscopic data on one-electron ions is presented. We show that in an appropriately weighted difference of the bound-electron gg factor and the ground state energy, nuclear structural effects can be effectively suppressed. This method is anticipated to deliver an independent value of α\alpha via existing or near-future combined Penning trap and x-ray spectroscopic technology, and enables decreasing the uncertainty of α\alpha by orders of magnitude.
