In 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.
Beta decay is a radioactive decay in which a beta ray is emitted from an atomic nucleus. During beta decay, the proton in the nucleus is transformed into a neutron and vice versa.
The 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.
Jun 6, 2024 · beta 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. The three processes are electron emission, positron (positive electron) emission, and electron capture.
Jun 21, 2024 · The first quantitative rate theory of beta decay was given by Enrico Fermi in 1934, and the essentials of this theory form the basis of modern theory. As an example, in the simplest beta-decay process, a free neutron decays into a proton, a negative electron, and an antineutrino: n → p + e− + ν.
Jul 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.
Beta decay is the most common form of radioactive decay. It happens in one of two ways. In one type of beta decay, an unstable atomic nucleus emits an electron and an antineutrino while converting a neutron to a proton.
Beta decay represents the transformation of a neutron from the nucleus of a radioactive element into a proton, an electron, also called a beta particel, and an antineutrino.
During beta minus decay, a neutron in an unstable nucleus transforms into a proton, releasing a high energy electron and antineutrino in the process. During beta plus decay, a proton in an unstable nucleus transforms into a neutron, releasing a high energy positron and neutrino in the process.
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. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e - +.
