Controlled nuclear transition for vastly more accurate clocks
(PHYSorg.com Physics)

A Russian scientist from Skobelitsyn Research Institute of Nuclear Physics, MSU theoretically substantiated that the speed of transition of thorium-229 from ground to excited state may be managed depending on external conditions. The frequency of the transitions may be increased or decreased by dozens of times. This effect will contribute to extremely precise clocks exceeding even the best atomic clocks. The article was published in Physical Review Letters.
