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.
7 Οκτ 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 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 .
2 Σεπ 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.
Beta decay or β decay represents the disintegration of a parent nucleus to a daughter through the emission of the beta particle. Beta-decay is governed by weak interaction. During beta decay, one of two down quarks changes into an up quark by emitting a W – boson (carries away a negative charge).
Theory of Beta Decay – Mechanism. Beta-decay or β decay represents the disintegration of a parent nucleus to a daughter through the emission of the beta particle. This transition (β– decay) can be characterized as: Beta-decay is governed by weak interaction. During beta decay, one of two down quarks changes into an up quark by emitting a ...
31 Ιουλ 2022 · Nuclear beta decay provides a sensitive and rich tool for studying the structure of atomic nuclei as well as assessing the limits of our understanding of the weak interaction. In this chapter the history of the topic is presented.
