Fundamental Tests of Special Relativity and the Isotropy of Spaceion rest frame [2] makes it interesting to reconsider experiments that can test for the one way speed of light. Indeed, high resolution laser spectroscopy appears to have the most to offer in terms of improved techniques and increased precisian for these tests.作者: Fsh238 時間: 2025-3-22 01:01

High Resolution Laser Spectroscopy of Atomic Hydrogenectroscopy of atomic hydrogen has been growing during the past two years, as documented by this and several following papers. At least four accurate new measurements of the Rydberg constant have been completed in 1986 [1–4]. Dramatic further improvements in spectral resolution and measurement accuracy should be achievable in the future.作者: APRON 時間: 2025-3-22 09:23
