A Nuclear Clock

Alex Kuzmich, Georgia Institute of Technology

(Session 2 : Friday from 13:00-13:45)

Abstract. Th-229 nucleus has an exceptionally low-lying first excited state, 7.5 eV relative to the ground state. As the nuclei are affected less by background electromagnetic fields than atoms, laser excitation of the nuclear transition has been proposed as a basis for an ultrastable clock. In this talk, I will report our progress towards trapping triply ionized Th-229.
