Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their ...

Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies.

Bind an electron to a reference ion—the team used the “hydrogen-like” carbon nucleus, stripped down to a single electron. The nucleus of that ion has a known, precise mass.

As electron mass is involved in fundamental physical constants, it is of significance to fundamental physics. A scale for absolute lightweights: Physicists used this Penning trap to determine the mass ...

The electron's mass is one of a few key parameters that govern the structure and properties of atoms, yet because the electron is so tiny, precisely measuring its atomic mass has been difficult.

Guest post by Andrew Grant. The electron has been weighed with unprecedented precision, researchers report February 19 in Nature.Its new and improved mass, 17 times as precise as the previous best ...

The electron atomic mass presented in this Letter, combined with the Rydberg constant 6, the atomic mass of rubidium 27 and an atom interferometric measurement of h/m Rb (ref. 26), yields a value ...

The atomic energy scale is related to our everyday world through the equivalence of the electron’s mass and energy, E = mc 2.However, while the speed of light, c, is a fixed constant by definition – ...

Unlike most of us, subatomic particles don't gain weight asthey get older. The mass of these tiny bits of matter has remained constantover the last 6 billion years, recent astronomical ...
