Fine Structure Anomalies and Search for Variation of the Fine Structure Constant in Laboratory Experiments
Configuration interaction in many-electron atoms may cause anomalies in the fine structure which make the intervals small and very sensitive to variation of the fine structure constant. Repeated precision measurements of these intervals over long period of time can put strong constrain on possible time variation of the fine structure constant. We consider the 5p 3P2,1,0 fine structure multiplet...
متن کاملSearch for Possible Variation of the Fine Structure Constant
Determination of the fine structure constant α and search for its possible variation are considered. We focus on a role of the fine structure constant in modern physics and discuss precision tests of quantum electrodynamics. Different methods of a search for possible variations of fundamental constants are compared and those related to optical measurements are considered in detail.
متن کاملRelativistic effects in Ni II and the search for variation of the fine structure constant
Theories unifying gravity and other interactions suggest the possibility of spatial and temporal variation of physical “constants” in the Universe. Detection of high redshift absorption systems intersecting the sight lines towards distant quasars provide a powerful tool for measuring these variations. In the present paper we demonstrate that high sensitivity to variation of the fine structure c...

متن کاملOn the cosmological variation of the fine structure constant
A phenomenological model is proposed to explain the recent observed cosmological variation of the fine structure constant as an effect of the quantum vacuum, assuming a flat universe with cosmological constant Λ in the cases (ΩM ,ΩΛ) equal to (0.3, 0.7) and (1, 0). Because of the fourth Heisenberg relation, the lifetime of the virtual pairs of the zero-point radiation must depend on the gravita...
