Laser Excitation of the Th-229 Nucleus

Laser Excitation of the Th-229 Nucleus

ABSTRACT: The 8.4 eV nuclear isomer state in Th-229 is resonantly excited in Th-doped CaF 2 crystals using a tabletop tunable laser system. A resonance fluorescence signal is observed in two crystals with different Th-229 dopant concentrations, while it is absent in a...
