  1. 25. Spectroscopy of HD+ and the Rydberg constant
    Vladimir Korobov (Joint Institute for Nuclear Research)
    10/06/2019, 09:45

    We consider recent experiments in the spectroscopy of the HD+ hydrogen molecular ion [1,2] as well as most recent achievements in theory. We want to show how the Rydberg constant may be deduced from theory-experiment comparison with a relative uncertainty close to 15 ppt.

  2. 26. Improving the hyperfine structure theory in hydrogen molecular ions
    Jean-Philippe Karr (Laboratoire Kastler Brossel)

    The hydrogen molecular ions H2+ and HD+ are promising systems for fundamental constants metrology. Their spectrum offer many ultra-narrow ro-vibrational transitions, the frequencies of which are sensitive to the proton-electron mass ratio, proton charge radius, and Rydberg constant [1]. Several projects aiming at high-accuracy measurements using Doppler-free spectroscopy schemes [2-4] are in...

  4. 24. Calculation of higher order corrections to positronium energy levels
    Gregory Adkins (Franklin & Marshall College)
    10/06/2019, 11:45

    I report on progress in the calculation of corrections to positronium energy levels of order $m \alpha^7$. Corrections at this level will be needed for the interpretation of the results of upcoming measurements. A procedure for the calculation of high order corrections has been developed based on the Bethe-Salpeter equation of dimensionally regularized NRQED and the method of regions. I...

  5. 2. High precision non-relativistic calculations for the nP (5<=n<=10) states of lithium atom
    Liming Wang (Henan Normal University)

    The non-relativistic energies of the low-lying states of lithium have been calculated to a relative accuracy of $ 10^{-15}$ [1, 2]. However, for higher-lying states, the accuracy in energy eigenvalues decreases significantly as the principal quantum number increases [3]. Drake has developed an effective method [4] to solve the Schrödinger equation of the Rydberg states of two-electron atomic...
