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.

Real-space charge-density imaging with sub-ångstrom resolution by four-dimensional electron microscopy. Nature , 2019 DOI: 10.1038/s41586-019-1649-6 Cite This Page : ...

He measured the electric charge on the electron and this is basically how he did it – by dropping oil drops. He shot some drops of oil (very tiny) into an area with a constant electric field.

Nothing is more emblematic of an electron than its negative charge. It’s the trait that determines how the particle behaves in electromagnetic environments, such as a wire’s electric field and ...

The two quasiparticles in those experiments were the "spinon," a neutral quasiparticle that behaves magnetically like an electron, and the "holon," a spinless excitation carrying electric charge.

Scanning transmission electron microscopy (STEM) can be used to detect electric charge density as well as image atoms. This new advance comes from researchers at the University of California, Irvine, ...

To create an electrical current, two particles, one with a negative charge (electron) and one with a positive charge (electron-hole), must separate despite being bound tightly together. These two ...
