Beta decay - Wikipedia
WEBIn nuclear physics, beta decay (β-decay) is a type of radioactive decay in which an atomic nucleus emits a beta particle (fast energetic electron or positron), transforming into an isobar of that nuclide.
7.2: Beta Decay - Physics LibreTexts
WEBThe beta decay is a radioactive decay in which a proton in a nucleus is converted into a neutron (or vice-versa). In the process the nucleus emits a beta particle (either an electron or a positron) and quasi-massless particle, the neutrino. Recall the mass chain and Beta decay plots of Fig. 7.
Beta Decay: Definition, Equation, Types, and Applications
WEBSep 2, 2024 · Beta decay is a type of radioactive decay where an unstable atom releases a high-energy, fast-moving particle to become more stable. The particle emitted during a beta decay is known as a beta particle, which can be an electron or a positron.

WEBThis process, called beta decay, is important in many physical processes. A Feynman diagram of beta decay is given in Figure 11.14 (a). The neutron emits a W − W − and becomes a proton, then the W − W − produces an electron and an antineutrino.

WEBbeta decay, any of three processes of radioactive disintegration by which some unstable atomic nuclei spontaneously dissipate excess energy and undergo a change of one unit of positive charge without any change in mass number.

Beta Decay
WEBBeta minus decay is the transformation of an unstable nucleus accompanied by the emission of an electron and an electron anti-neutrino. It happens when a neutron changes into a proton. The electron and electron anti-neutrino come from the decay of the W-particle (here the W - -particle).
Beta Decay Definition and Examples - Science Notes and Projects
WEBJul 3, 2022 · Beta decay is a type of radioactive decay that releases an energic electron or positron (the antimatter version of an electron). The process occurs when an atomic nucleus is unstable because it has too many protons or neutrons. In beta minus decay (β −), a neutron decays into a proton, an antineutrino, and an electron.
WEBThis decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom of a different type, named the daughter nuclide. The three principal modes of decay are called the alpha, beta and gamma decays.

WEBBeta decays. Beta particles are electrons or positrons (electrons with positive electric charge, or antielectrons). Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
