Researchers in Argonne's Physics Division teamed up to conduct the most precise measurement ever made of the charge radius — one aspect of the size — of the Borromean nucleus of helium-6. ARGONNE, Ill ...

This allows the nuclear radius to be determined with high precision. With the measurement of helium-3, the experiments on light muonic atoms have now been completed for the time being. The researchers ...

The covalent radius (a measure of how large individual atoms are) shows different trends if you are moving across a period or down a group. A comparison of the relative covalent radii of atoms is ...
