تعريف beta çözünmesi في التركية الإنجليزية القاموس.

beta decay

A nuclear reaction in which a beta particle (electron or positron) is emitted

A nuclear reaction in which beta particles (electrons or positrons) are absorbed by or emitted from the nucleus of an atom

A nuclear reaction in which beta particles (electrons, -, or positrons, +) are absorbed by or emitted from the nucleus of an atom

radioactive decay by conversion of a neutron into a proton, leaving the atomic mass number the same while increasing the atomic number, e g decay of carbon-14 (6 protons, 8 neutrons) to nitrogen-14 (7 of each) An electron is emitted (as is a neutrino) Conversion of a proton to a neutron, with emission of a positron, is also called beta decay, but such conversions more usually occur by the capture of an electron (which is indeed called electron capture)

The radioactive decay of a nucleus via the reaction n -> p + e- + or p -> n + e+ + n; so called because an electron or antielectron is also known as a beta particle

The radioactive decay of an atomic nucleus accompanied by emission of a beta particle. Any of three processes of radioactive disintegration in which a beta particle is spontaneously emitted by an unstable atomic nucleus in order to dissipate excess energy. Beta particles are either electrons or positrons. The three beta-decay processes are electron emission, positron emission, and electron capture. The process of beta decay increases or decreases the positive charge of the original nucleus by one unit without changing the mass number. Though beta decay is in general a slower process than gamma or alpha decay, beta particles can penetrate hundreds of times farther than alpha particles. Beta decay half-lives are a few milliseconds or more. See also radioactivity

the breakdown of a neutron into a proton, which remains in the nucleus, and an electron, which is emitted as a beta particle

The process of radioactive decay in which a neutron loses a beta particle, which is physically identical to an electron This increases the atomic number of the atom by one by turning the neutron into a proton The atom's atomic mass number stays the same because the total number of protons and neutrons remain the same The most common form of radioactive decay

The emission of electrons or positrons (particles identical to electrons, but with a positive electrical charge) from the nucleus of an element in the process of radioactive decay of the element

The decay of a parent nucleus into a daughter nucleus by the emission of a beta particle when one of the neutrons in the nucleus transforms into a proton The atomic weight of the nucleus remains the same, but the atomic number increases by one

radioactive decay of an atomic nucleus that is accompanied by the emission of a beta particle

The decay process where an isotope emits an electron (called a beta particle), converting one neutron into a proton to conserve electrical charge This causes the isotope to become a different element, for example, the beta decay of tritium 3H, with one proton and two neutrons, produces helium 3He, with two protons and one neutron
