Explore: Alpha Particles

Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to the nucleus

adapt these equations to alpha particle scattering on the assumption that alpha particles are point charges much like beta particles. These equations will

alpha particle X-ray spectrometer (APXS) is a spectrometer that analyses the chemical element composition of a sample from scattered alpha particles and

its alpha particles, a theoretical derivation of the empirical Geiger–Nuttall law. Alpha emitters are used in smoke detectors. The alpha particles ionize

radiation: alpha particles that did not show up on the Becquerel plates because they were easily absorbed by the black wrapping paper beta particles which

explain why most alpha particles do not scatter to any measurable degree – they fly past too far from the charge – and yet particles that do pass very

Alpha spectrometry (also known as alpha(-particle) spectroscopy) is the quantitative study of the energy of alpha particles emitted by a radioactive nuclide

10 electronvolts (eV) Ionizing subatomic particles include alpha particles, beta particles, and neutrons. These particles are created by radioactive decay, and

x-rays, and gamma radiation (γ) particle radiation consisting of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β)

denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles. The constituent
