Short-Lived Radioactive Molecules

Molecular systems provide highly sensitive laboratories for exploring the possible violation of fundamental symmetries and search for new physics beyond the standard model physics [1-4].  Radioactive molecules composed of heavy and deformed short-lived isotopes are predicted to offer superior sensitivity to investigate parity- and time-reversal violation effects [5-7]. However, the experimental knowledge of short-lived radioactive molecules is scarce, and quantum chemistry calculations constitute the only source of spectroscopic information. 

Recently, our group at CERN, developed an experimental technique to perform laser spectroscopy measurements of radioactive molecules [8]. We have achieved the first ever laser spectroscopy study of a short-lived radioactive molecule [9]. These results open up new opportunities in the design, manipulation and study of short-lived radioactive molecules for many-body physics, astrophysics, nuclear structure, and in the search for new physics beyond the Standard Model of particle physics.
