Puzzling problem: Karsten Schuhmann (left) and Aldo Antognini of the Paul Scherrer Institute inspect the laser system that was used for the laser spectroscopy measurements on muonic deuterium.
A discrepancy in the measured size of the “deuteron” increases the chance that something is amiss in our understanding of atoms. The same group that discovered a curious discrepancy in measurements of ...
A new measurement method suggests that the proton, a crucial subatomic particle in the Universe, is smaller than previously believed. All visible matter in the ...
Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimetre. This is precisely the ...
TORONTO, September 5, 2019 - York University researchers have made a precise measurement of the size of the proton - a crucial step towards solving a mystery that has preoccupied scientists around the ...
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, ...
