Definition of beta particle in English: beta particle(also beta ray) noun Physics A fast-moving electron emitted by radioactive decay of substances (originally regarded as rays). 〔物理〕 β 粒子 Example sentencesExamples - Next smaller in mass is the beta particle, which is identical in mass and charge to an electron.
- They were doing rather… sexual things to the corpse, and were sliding glowing beta particle knives across her limbs as they did so.
- The emitted beta particle travels through air at close to the speed of light.
- Beta emissions involve the loss of an electron from the nucleus as a beta particle during the conversion of a neutron into a proton.
- When a radioactive nucleus disintegrates by emitting an alpha or beta particle, it changes into a different nucleus - that is, one with a different number of protons and/or neutrons.
- When it decays it emits a beta particle and a gamma ray, leaving behind a protactinium - 234 atom.
- During this process (mediated by a virtual W - particle) the nucleus expels a negative beta particle (electron or negatron) as radiation.
- When a nucleus decays, through the emission of either an alpha or beta particle, the resulting new nucleus is often left in an excited state.
- Its existence was suggested to explain missing energy and angular momentum when a beta particle was emitted from a radioactive element.
- She got hit in the hip with a beta particle dagger, but it missed most major tendons.
- Tritium has a half-life of 12.3 years and emits a very weak beta particle.
- The cobalt nucleus decays to nickel - 60 by emitting a beta particle and two gamma rays.
- A beta particle is an electron that could make it just a little way into the skin, while an alpha particle is a charged helium nucleus that will bounce right off of you.
- Uranium - 238 emits an alpha particle and changes to thorium - 234, which then emits a beta particle to allow it to change to palladium - 234.
- Its nucleus emits a low-energy beta particle, leaving behind an isotope of helium, helium - 3, that has a single neutron in its atomic nucleus.
- A radioactive atom used in nuclear medicine that shows radioactive disintegration and emits alpha and beta particles or gamma rays.
- Adding a neutron, which has one unit of mass, to 238 U gives 239 U, which decays rapidly to a new element by emitting a beta particle.
- The weak nuclear force is involved, and the neutron is converted into a proton when the beta particle is emitted.
- Tritium is a radioactive element that decays by the loss of a beta particle to become a helium - 3 isotope.
- When this occurs, the electron shoots out of the atom and is called a beta particle, a type of radioactivity.
