| Abstract: | We have applied experimental techniques that were developed for use in atomic frequency standards andclocks to investigations of local Lorentz invariance, the linearity of quantum mechanics, andanomalous long-range spin-dependent forces. These experiments used a hyperfine transition in9Be+ ions in a Penning trap. Recently, we have studied hyperfine transitions in199Hg+ ions in a linear rf trap. Hg+ ions might be used for similar investigations in the future.Work of the National Institute of Standards andTechnology. Not subject to US copyright. |
