Non-perturbative calculation of the two-loop Lamb shift in Li-like ions
V. A. Yerokhin, P. Indelicato, V. M. Shabaev
A calculation valid to all orders in the nuclear-strength parameter is presented for the two-loop Lamb shift, notably for the two-loop self-energy correction, to the 2p-2s transiti…
A linear Stark shift in dressed atoms as a signal to measure a nuclear anapole moment with a cold atom fountain or interferometer
Marie-Anne Bouchiat
We demonstrate theoretically the existence of a linear dc Stark shift of the individual substates of an alkali atom in its ground state, dressed by a circularly polarized laser fie…
Relativistic calculations of pionic and kaonic atoms hyperfine structure
Martino Trassinelli, Paul Indelicato
We present the relativistic calculation of the hyperfine structure in pionic and kaonic atoms. A perturbation method has been applied to the Klein-Gordon equation to take into acco…
Highly charged ion X-rays from Electron-Cyclotron Resonance Ion Sources
Paul Indelicato, S. Boucard, D. S. Covita +13
Radiation from the highly-charged ions contained in the plasma of Electron-Cyclotron Resonance Ion Sources constitutes a very bright source of X-rays. Because the ions have a relat…
Pump-probe measurement of atomic parity violation in caesium with a precision of 2.6%
Michel Lintz, Jocelyne Guéna, Marie-Anne Bouchiat
We present the atomic parity violation measurements made in Cs vapour using a pump-probe scheme. After pulsed excitation of the 6S-7S forbidden transition in the presence of a long…
Proposal for new experimental schemes to realize the Avogadro constant
F. Biraben, M. Cadoret, P. Clad +7
We propose two experimental schemes to determine and so to realize the Avogadro constant at the level of 10 or better with a watt balance experiment and a cold atom…
