Experiments at CERN and the Accelerator Laboratory in Jyväskylä, Finland, have revealed that the radius of an exotic nucleus of aluminum, 26m Al, is much larger than previously thought. The result, ...

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 ...

New standards in nuclear physics An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The ...

In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the ...
