alpha particle
The positively charged, high-energy, particles emitted from the nucleus of a radioactive atom.

They consist of two neutrons and two protons and so they are identical to the nucleus of a helium atom and are one of the products of the spontaneous disintegration of radioactive elements; such as, radium and thorium.

The process of emission, alpha decay, transforms one element into another, decreasing the atomic (or proton) number by two and the atomic mass (or nucleon number) by four.

It is a product of disintegration of various isotopes of both natural and artificial radioactive elements.

This entry is located in the following unit: alpha; A, α + (page 1)
beta particle
1. A high-speed electron or positron, especially one emitted in radioactive decay.
2. A small electrically charged particle thrown off by many radio-active materials.

It is identical to the electron and possesses the smallest negative electric charge found in nature.

Beta particles emerge from radioactive material at high speeds, sometimes close to the speed of light.

3. An electron emitted at high velocity from a radioactive atom that is undergoing spontaneous disintegration.

Beta particles do not exist in the nucleus but are created during disintegration, or beta decay, when a neutron converts to a proton to emit an electron.

upsilon particle
1. In particle physics, a heavy, short-lived particle consisting of a bottom quark bound to its anti-quark; thus, the fifth-quark analog to the J particle.

Eleven additional particles with this quark structure have been identified so far.

2. One of a family of elementary particles having about ten times the mass of the proton and consisting of an atom-like combination of a bottom quark with its anti-quark.

This entry is located in the following units: hyper-, hyp- (page 20) xi; Ξ, ξ + (page 1)
xi-minus particle
A xi hyperon that carries a unit negative charge designated Ξ-; also known as "cascade particle".

A hyperon is a comparatively massive baryon that may be unstable or partially stable and is short-lived.

A baryon is a subatomic particle belonging to a group that undergoes strong interactions, has a mass greater than or equal to that of the proton (a stable, positively charged elementary particle), and consists of three quarks.
