Abstract:
Precision knowledge of energies of autoionizing levels is highly demanded for diagnostics of hot laboratory plasmas, astrophysical and fusion research. Their energies, however, cannot be directly calculated by conventional methods such as
coupled-cluster and configuration-interaction. Indeed, autoionization levels are embedded to the positive energy continuum and, as a result, cannot be described by square-integrable functions. Complex coordinate rotation detaches the autoionization levels
from the continuum. Wave functions of these states, therefore, become square-integrable and can be investigated with conventional many-electron methods. Here we combine the complex scaling approach with the configuration-interaction method in order to solve
many-electron Dirac-Coulomb-Breit equation.
