Experimental test of special relativity by laser spectroscopy
The Doppler-free laser-spectroscopic frequency measurement of Doppler-shifted optical lines in forward and backward direction of a fast ion beam permits a sensitive test of the relativistic Doppler-formula and, hence, the relativistic time dilation factor γSR 1⁄4 ð1 ν2 c2 1=2. An experiment on metastable Li, stored at a velocity of v= 0.064c in the Heidelberg heavy-ion storage ring TSR, has con...
متن کاملTest of time dilation using stored Li+ ions as clocks at relativistic speed.
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of β=v/c=0.338 in the storage ring ESR at Darmstadt. A Λ-type three-level system within the hyperfine structure of the 7Li+3S1 →3P2 line is driven by two laser beams aligned parallel and antiparallel relative to the ion beam. The lasers' Doppler shifted frequencies require...
متن کاملAberration of Erythrocyte Sedimentation Rate by Zinc Nanoparticles
Dear Editor, erythrocyte sedimentation rate (ESR) is a useful basic clinical pathology laboratory investigation. It can be helpful in diagnosis and follow-up of several diseases. At present, a new automated method with proven reliability is available for ESR test (1). Here, the authors report on observation on a laboratory experiment to test the effect of zinc nanoparticles on ESR results. The...
متن کاملThe Relationship Between Reaction Time of Electrical Stapedius Reflex and Auditory Performance in Cochlear-Implanted Children
Background: A common concern in some cochlear-implanted children is the lack of desired progress in auditory and listening skills. Such a concern remains despite proper verbal processor programming, additional disabilities, and continuous participation in hearing rehabilitation programs. A more detailed assessment of pathways and centers of the auditory processing at the lower end of the brain ...
متن کاملTest of relativistic time dilation with fast optical atomic clocks at different velocities
Time dilation is one of themost fascinating aspects of special relativity as it abolishes the notion of absolute time. It was first observed experimentally by Ives and Stilwell in 1938 using the Doppler effect. Here we report on a method, based on fast optical atomic clocks with large, but different Lorentz boosts, that tests relativistic time dilation with unprecedented precision. The approach...
