For efficient cooling, ytterbium ions are ... cooling ions within the crystal structure, ensuring optimal performance. When tested against other cutting-edge atomic clocks, including a strontium ...

The international collaboration team was even able to use this data to obtain direct information about the deformation of the atomic nucleus along the ytterbium isotope chain. This can provide new ...

To obtain this result, physicists from PTB compared caesium and ytterbium atomic clocks ... which is responsible for the structure and the cohesion of atomic nuclei. Variable fundamental constants ...

Together with new calculations of the structure of atomic nuclei ... such isotope shifts in the element ytterbium. This sent the world of atomic physicists into a spin: Could this anomaly be ...

At the heart of this change is a new kind of atomic clock ... as the "clock" and three ytterbium ions that cool it down. These ions interact to form a crystal-like structure held in place by ...

Because of their extreme atomic structure, highly charged ions can ... argon ions and compared the ticking with the existing ytterbium ion clock at PTB. To do this, they had to analyse the system ...

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 ...

1 The electronic structure of sodium can also be shown in a diagram. Each dot represents an electron. Since the atomic number of oxygen is 8, it will have 8 protons in the nucleus. An atom of ...
