Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

A number of chemically minded readers have pointed out that, thanks to a nearby rare-earth mine, it is home not just to yttrium and ytterbium but also the elements terbium and erbium. Joel ...

One of NIST's ytterbium lattice atomic clocks. NIST physicists combined two of these experimental clocks to make the world's most stable single atomic clock. The image is a stacked composite of ...

Originally spotted in ytterbium atoms, the anomaly turns out to have a more ... of heavy atomic nuclei and the physics of neutron stars. Isotopes are forms of an element that have the same number of ...

dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes). There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing, and ...

The Company’s scientists continue to optimize various steps of the process but have overcome the major problems inherent in any new process and are successfully enriching Ytterbium-176 that will ...
