The atom is neutral as it has two positive protons and two negative electrons. A helium atom that has lost or gained an electron is an ion.

The Facility for Rare Isotope Beams achieved the highest-power beam of uranium ions ever in the world. "We're already now in ...

At the cutting-edge Facility for Rare Isotope Beams, researchers have precisely measured the mass of aluminum-22, revealing ...

The electric and magnetic fields of an electrostatic accelerator system are used to filter out other isotopes from the ion beam. The high velocity means that molecules can be destroyed and removed ...

the resulting collisions cause the ions to lose or gain neutrons or protons and become unstable. This causes them to create thousands of rare isotopes, themselves highly unstable — often ...

Measurements of very rare isotopes are key to testing nuclear theory ... Next, the beam was sent to the Low Energy Beam and Ion Trap (LEBIT) facility, where the ions were injected into a device ...
