In beta decay a neutron decays into a
WebA beta particle, also called beta ray or beta radiation (symbol β ), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons respectively. [2] WebMar 3, 2024 · 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 …

WebIn beta decay, a neutron-rich nuclide decays by the conversion of a neutron into a proton and an electron accompanied by the emission of an antineutrino. The antineutrino is an antiparticle (same mass but opposite electric charge and magnetic moment) of the neutrino. It is a lepton like an electron which is an elementary particle of spin ½. WebIn beta decay, one of the down quarks that composes a neutron (two down and one up quarks) in C-14 decays via the weak interaction into an up quark, leaving a proton (two up and one down quarks). The W⁻ boson from the weak interaction quickly decays into an electron and an anti-neutrino.
The two types of beta decay are known as beta minus and beta plus. In beta minus (β ) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β ) decay, a proton is converted to a neutron and the process creates a positron and an electron … See more In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of … See more In β decay, the weak interaction converts an atomic nucleus into a nucleus with atomic number increased by one, while emitting an electron ( See more In all cases where β decay (positron emission) of a nucleus is allowed energetically, so too is electron capture allowed.
