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 ...

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 ...

The fine structure constant ... put in place a leap second every few years." As well as ytterbium, aluminum, mercury and strontium atomic clocks are also being developed around the world, to ...

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 ...

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 ...

But researchers have managed to develop an experimental atomic clock based on ytterbium atoms that boasts precision comparable to that of NIST-F1. The humble second was chosen as the International ...

The method chosen depends on the type of mixture. Atomic structure - AQA Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. The numbers of subatomic ...

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 ...
