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