Background: A ruler for a proton In order to measure the charge radius of the proton, the researchers use the electronic interactions in a hydrogen atom and take into account the tiniest details ...

The atom would make the jump to the higher ... Could it be possible to reconcile the raw data with the smaller radius from muonic hydrogen? It seems that this fix has also been ruled out.

This formed an exotic, heavier version of the hydrogen atom. And here, measuring the proton's radius produced an entirely different value—something that shouldn't have happened. This “proton ...

The resulting atom, called muonic hydrogen, can be measured during the ... very high-precision value for the proton's radius. Just one small problem: it differs from the other measurements by ...

The Golden ratio which appears in the geometry of a variety of creations in Nature is found to arise right in the Bohr radius of the hydrogen atom due to the opposite charges of the electron and ...

tiny—less than two trillionths of a millimeter across—so teasing out their radius requires exacting techniques. Researchers can fire a beam of electrons at a hydrogen atom, whose nucleus ...

"The average distance between the electron and its nucleus can be as large as several hundred nanometers — that is more than 1,000 times the radius of a hydrogen atom," Joachim Burgdörfer ...

The nucleus of a hydrogen atom consists of a single proton, making this atom a suitable platform for determining the proton’s intrinsic properties. One such property is the proton charge radius ...
