Alpha particles are positively charged particles that comprise two protons, two neutrons, and zero electrons. A single particle's mass is 4 amu (6.642×10−4 g), ...

Alpha particles lurk at the surface of neutron-rich nuclei Date: January 21, 2021 Source: RIKEN Summary: Scientists have found evidence of alpha particles at the surface of neutron-rich heavy ...

Alpha particles are a powerful cancer-killing tool, directly damaging tumour cell DNA regardless of the level of oxygenation or cell cycle stage. The downside of alpha particles is their extremely ...

In fact, beta particles are electrons—the fundamental particles with a negative charge. The mass of an alpha particle is more than 7,000 times larger than that of a beta particle.

Alpha Centauri is the star system closest to our Solar System, and it is likely that particles from it could be making their way over to or already be in our stellar neighborhood. To know what to ...

Researchers have created gold nanoparticles that allow an alpha particle-emitting element to be directed to small cancer tumors.

Although alpha particles carry powerful radiation, they cannot penetrate the skin, and can even be blocked by something as thin as paper. ...

Alpha particles deposit much greater energy (and ionization) per unit length — enough to leave an ion trail dense enough for the imposed electric field to literally ‘connect the dots’ and ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...
