    Oral presentation

    In this work, we present benchmark variational calculations for the ground and 15 lowest bound excited 1S and 1P states of doubly ionized Carbon (C III). The nonrelativistic wave function of each of these states is generated in an independent calculation by expanding it in terms of a large number (8,000−12,000) of all-electron explicitly correlated Gaussian functions (ECG) who’s nonlinear...

    spectroscopy of exotic atoms
    Poster presentation

    We are developing a high intensity, low-emittance atomic muonium (Mu $= \mu^+ + e^-$) beam, which would enable improving the precision of Mu spectroscopy measurements and may be amenable to a direct measurement of the gravitational acceleration of Mu. Measuring the free fall of Mu atoms would be the first test of the weak equivalence principle using elementary antimatter of the second...

    quantum standards
    Poster presentation

    Defining the values of constants is the best method to define units since it separates the definition from the realization. For example, there are two very different methods to realize the kg. In the future, there can be other methods of realizing the kg that adapt to possible advancements in technology without changing the definition. With the reform of the SI system, all but one of the units...

    Poster presentation

    The ASACUSA-CUSP experiment located at CERN’s antiproton decelerator aims at measuring the ground state hyperfine splitting of antihydrogen (H̄) using a beam technique to test CPT symmetry. For this purpose, a beam of cold (~50K) hydrogen has been developed to characterize the antihydrogen spectroscopy apparatus [1]. Beyond serving as a test bench for the H̄ experiment, the hydrogen beamline...

    spectroscopy of exotic atoms
    Poster presentation

    The ASACUSA-Cusp experiment aims to perform spectroscopy of the hyperfine structure of antihydrogen by producing a beam of cold, spin polarised, ground state antihydrogen. The beam will be produced by mixing positrons and antiprotons in our unique Cusp trap which uses a pair of superconducting coils in an anti-Helmholtz configuration to produce a magnetic field capable of both confining the...

  12. 36. Precision Spectroscopy of Atomic and Molecular Negative Ions at the Frankfurt Low Energy Storage-Ring FLSR

    precision measurements in fundamental physics, astrophysics and cosmology
    Poster presentation

    Negative ions are complex quantum systems in which an additional electron is bound to the neutral atom or molecule by a weak van der Waals force resulting from polarization of the electron shell. This binding depends strongly on the electron configuration of the shell and is therefore sensitive to electron correlation effects. Due to the lack of long ranged Coulomb force the resulting binding...

    spectroscopy of exotic atoms
    Poster presentation

    The antikaon-nucleon interaction in the low-energy regime of QCD is, to this day, not fully understood and theoretical models need experimental constraints. Kaonic atoms are ideal candidates to study this regime of QCD including strangeness without the need for extrapolation to zero relative energy. The SIDDHARTA-2 experiment, located at the DA$\Phi$NE collider at LNF in Italy, can provide...

    Dr Wei-Qiang WEN
    quantum electrodynamics of bound systems
    Poster presentation

    High precision spectroscopy of the low-lying dielectronic resonances in fluorine-like Ni19+ ions was studied by employing the electron-ion merged-beams method at the heavy-ion storage ring CSRm. The measured dielectronic-recombination (DR) resonances are identified by comparison with relativistic calculations utilizing the flexible atomic code (FAC). The lowest-energy resonance at about 86 meV...
