Reevaluation of the role of nuclear uncertainties in experiments on atomic parity violation with isotopic chains
Andrei Derevianko, Sergey Porsev
In light of new data on neutron distributions from experiments with antiprotonic atoms [ Trzcinska {\it et al.}, Phys. Rev. Lett. 87, 082501 (2001)], we reexamine the role of nucle…
High-accuracy relativistic many-body calculations of van der Waals coefficients C_6 for alkaline-earth atoms
Sergey Porsev, Andrei Derevianko
Relativistic many-body calculations of van der Waals coefficients C_6 for dimers correlating to two ground state alkaline-earth atoms at large internuclear separations are reported…
High-precision determination of transition amplitudes of principal transitions in Cs from van der Waals coefficient C_6
Andrei Derevianko
A method for determination of atomic dipole matrix elements of principal transitions from the value of dispersion coefficient C_6 of molecular potentials correlating to two ground-…
Correlated many-body treatment of Breit interaction with application to cesium atomic properties and parity violation
Andrei Derevianko
Corrections from Breit interaction to basic properties of atomic 133Cs are determined in the framework of third-order relativistic many-body perturbation theory. The corrections to…
On the feasibility of cooling and trapping metastable alkaline-earth atoms
Andrei Derevianko
Metastability and long-range interactions of Mg, Ca, and Sr in the lowest-energy metastable state are investigated. The calculated lifetimes are 38 minutes for Mg*, 118 min…
High-precision calculations of electric-dipole amplitudes for transitions between low-lying levels of Mg, Ca, and Sr
S. G. Porsev, M. G. Kozlov, Yu. G. Rakhlina +1
To support efforts on cooling and trapping of alkaline-earth atoms and designs of atomic clocks, we performed ab initio relativistic many-body calculations of electric-dipole trans…
