Dual kinetic balance approach to basis set expansions for the Dirac equation
V. M. Shabaev, I. I. Tupitsyn, V. A. Yerokhin +2
A new approach to finite basis sets for the Dirac equation is developed. It solves the problem of spurious states and, as a result, improves the convergence properties of basis set…

Relativistic calculations of isotope shifts in highly charged ions
I. I. Tupitsyn, V. M. Shabaev, J. R. Crespo Lopez-Urrutia +3
The isotope shifts of forbidden transitions in Be- and B-like argon ions are calculated. It is shown that only using the relativistic recoil operator can provide a proper evaluatio…
