The fine structure constant α is a keystone for the determination of other fundamental physical constants, especially the ones involved in the framework of the future International System of units. This paper presents the Paris experiment, where the fine structure constant is determined by measuring the recoil velocity of a rubidium atom when it absorbs a photon.
