Mesures de fréquences et calculs de haute précision en physique atomique et moléculaire

Abstract : The work presented in this manuscript belongs to the two fields of - optical frequency metrology and - three body coulomb problem and the proton to electron mass ratio. In the first part, the secundary frequency standard based on the two photon transition in rubidium is presented. Its metrological characteristics are discussed as well as the measurement of its absolute frequency and the applications to the hydrogen atom spectroscopy. The second part is devoted to the numerical calculation of the eigenenergies and eigenfunctions of the hydrogen molecular ion, as well as to some resonances of the exotic species where the electron is replaced by a muon or a pion. From the eigenfunctions, the two photon transition probabilities between vibrational states of H2+ are obtained. A scheme to accuratly determine of the proton to electron mass ratio using H2+ spectroscopy is proposed and analysed. Finally, a new calculation method of the three body coulomb problem in two dimensions is proposed, and applied to the case of helium.
