Precision spectroscopy and laser-cooling scheme of a radium-containing molecule
/ Udrescu, S M (MIT) ; Wilkins, S G (MIT) ; Breier, A A (Kassel U.) ; Athanasakis-Kaklamanakis, M (CERN ; Leuven U.) ; Ruiz, R F Garcia (MIT) ; Au, M (CERN ; Mainz U.) ; Belošević, I (TRIUMF) ; Berger, R (Philipps U. Marburg) ; Bissell, M L (Manchester U.) ; Binnersley, C L (Manchester U.) et al.
Molecules containing heavy radioactive nuclei are predicted to be extremely sensitive to violations of the fundamental symmetries of nature. The nuclear octupole deformation of certain radium isotopes massively boosts the sensitivity of radium monofluoride molecules to symmetry-violating nuclear properties. [...]

In-source and in-trap formation of molecular ions in the actinide mass range at CERN-ISOLDE
/ Au, M. (CERN ; Mainz U.) ; Athanasakis-Kaklamanakis, M. (CERN ; Leuven U.) ; Nies, L. (CERN ; Greifswald U.) ; Ballof, J. (CERN ; Michigan State U., East Lansing (main) ; Philipps U.

The use of radioactive molecules for fundamental physics research is a developing interdisciplinary field limited dominantly by their scarce availability. In this work, radioactive molecular ion beams containing actinide nuclei extracted from uranium carbide targets are produced via the Isotope Separation On-Line technique at the CERN-ISOLDE facility.

Opportunities for Fundamental Physics Research with Radioactive Molecules
/ Arrowsmith-Kron, Gordon (Michigan State U.) ; Athanasakis-Kaklamanakis, Michail (CERN ; Leuven U.) ; Au, Mia (CERN ; Mainz U.) ; Ballof, Jochen (CERN ; Michigan State U.) ; Berger, Robert (Philipps U. Marburg) ; Borschevsky, Anastasia (U. Groningen, VSI) ; Breier, Alexander A. (Kassel U.) ; Buchinger, Fritz (McGill U.) ; Budker, Dmitry (Darmstadt, GSI ; UC, Berkeley) ; Caldwell, Luke (JILA, Boulder ; U. Colorado, Boulder ; Colorado U.) et al.
Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei.

Theoretical aspects of molecular spectroscopy.
/ Johnston, Karl (speaker) (CERN) ; Berger, Robert (speaker) (Philipps Universitaet Marburg (DE))
Overview of theoretical molecular spectroscopy
This lecture series aims to provide a quick overview of the underlying theoretical concepts of molecular spectroscopy. It is planned to discuss the Born-Oppenheimer picture/cartoon and resulting consequences, term values and effective Hamiltonians, symmetries and selection rules, coupling schemes in diatomic molecules and various aspects of rotational, vibrational and electronic spectroscopy as well as their prediction by quantum chemical approaches.
