Laser Spectroscopy Studies of Radium-Containing Molecules

ORAL · Invited

Abstract

Recent advancements in the experimental manipulation and interrogation of molecules are opening new avenues for exploring the fundamental laws of the universe. In particular, molecules that incorporate radioactive, heavy, octupole-deformed nuclei, such as radium, offer increased sensitivity for detecting yet-to-be-discovered parity- and time-reversal-violating nuclear properties. This talk will present recent highlights and perspectives from laser spectroscopy experiments on radium monofluoride molecules, RaF. The relevance of these experiments in addressing open questions in nuclear and particle physics will also be discussed.
