High partial waves contribution in calculations of the polyvalent atoms
M. G. Kozlov
High accuracy calculations of atomic properties require using long basis sets. In particular, it is necessary to include large number of partial waves and estimate truncation corre…
Self-energy correction to the E1 transition amplitudes in hydrogen-like ions
M. G. Kozlov, M. Y. Kaygorodov, Yu. A. Demidov +1
We present calculations of the self-energy correction to the transition amplitudes in hydrogen-like ions, performed to all orders in the nuclear binding strength parameter. Ou…
QED calculations of the E1 transition amplitude in neon-like iron and nickel
M. G. Kozlov, V. A. Yerokhin, M. Y. Kaygorodov. +1
We calculated QED corrections to the transition amplitudes in Ne-like iron and nickel. For the transitions the dominant effect came from the many-electron mixing,…
Basis set calculations of heavy atoms
M. G. Kozlov, Yu. A. Demidov, M. Y. Kaygorodov +1
Most modern calculations of many-electron atoms use basis sets of atomic orbitals. An accurate account for the electronic correlations in heavy atoms is very difficult computationa…
Precision calculations of atoms with few valence electrons
M G Kozlov
We discuss the possibility of using pair-equations for the construction of the effective Hamiltonian for valence electrons of an atom. The low-energy part of atomic s…
