New Publication by the PTB group

Ekkehard Peik and Maxim Okhapkin published a new review article on the unique low-energy two-level system in the nucleus of Th-229. This up-to-date review paper describes all past and present approaches to find the isomer transition and outlines possible schemes for a future optical clock. The article “Nuclear clocks based on resonant excitation of gamma-transitions” has been published in a special issue entitled “The measurement of time” in the French series of books Comptes Rendus Physique, edited by Christophe Salomon.
