Description
Summary:Recently a new wave of interest to spectroscopy of radioactive compounds has raised due to successful applications of the new experimental ISOL/CRIS technique to optical spectroscopy of radium monofluoride molecules. This opens great prospects to searches of the effects connected with ``new physics'' which point on deviations of the physical laws from those established by Standard Model of elementary particles. Considerable advantages in experiments for search for such effects would be provided by the abilities to trap the working molecules, their laser-coolability and presence of co-magnitometer molecular states and also a variety of accessible nuclear isotopes of the elements in the molecule with different nuclear multipole moments. Laser-coolable polyatomic molecular ions containing Ra nuclei shall meet the above criteria and in the present article we are considering a number of prospective molecular ions and calculating their electronic structure and molecular properties.
