  • Direct detection of the 229Th nuclear clock transition has been achieved, placing direct constraints on transition energy and half-life; these results are a step towards a nuclear clock, nuclear quantum optics and a nuclear laser.

  • Laser excitation of the 229Th isomer, potentially relevant for nuclear clocks, is reported in thorium fluoride thin films, which are less radioactive and amenable to integration compared with existing thorium-doped crystals.
