A New Option for a Search for Alpha Variation: Narrow Transitions with Enhanced Sensitivity
arXiv:physics/0511180 · doi:10.1088/0953-4075/39/8/011
Abstract
We consider several transitions between narrow lines that have an enhanced sensitivity to a possible variation of the fine structure constant, alpha. This enhancement may allow a search to be performed with an effective suppression of the systematic sources of uncertainty that are unavoidable in conventional high-resolution spectroscopic measurements. In the future this may provide the strongest laboratory constraints on alpha variation.
