Measurement of the ratio h/mRb and determination of the fine structure constant
Résumé
We present a review of the most precise determinations of the fine structure constant α which are obtained in different domains of physics. We describe the measurement of the ratio h/mRb between the Planck constant and the mass of Rubidium atom which leads to a precise value of α which is very few dependent of the QED. Finally, we present a review of the different determinations of the von Klitzing constant RK.
