  Radioactive decay is the transmutation of one subatomic particle into another. In most instances, what happens is that existing particles move to new configurations. However in . The efforts of the alchemists failed because they relied on chemical interactions rather than nuclear interactions. Interactive. Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. (or beta decay), this process occurs due to the weak nuclear force.

The weak interaction is responsible for radioactive decay, including the above Beta-minus decay. The weak interaction (the weak force or weak nuclear force) of particle physics is one of the four known fundamental interactions of nature, alongside the strong interaction, electromagnetism, and gravitation.   Weak interactions (the term "force" is not really applicable over the distances where weak interactions are relevant) are responsible for changing an up quark do a down quark or vice versa depending on whether you have beta+ or beta- decay. In this process the weak force also creates the electron/positron and the accompanying neutrino and some.

Weak Nuclear Force. This type of force is experienced by both baryons and leptons. The exchange particle for this type of force is the W or the K boson. This force is responsible for decay interactions (such as beta decay) and interactions where strangeness is not conserved or where quarks change flavour (or type). Electromagnetic Force. This clear and concise introduction to nuclear physics provides an excellent basis for a core undergraduate course in this area. The book opens by setting nuclear physics in the context of elementary particle physics and then shows how simple models can provide an understanding of the properties of nuclei, both in their ground states and excited states, and also of the nature of nuclear /5(3).

Beta decay is governed by the weak beta decay one of two down quarks changes into an up quark by emitting a W – boson (carries away a negative charge). The W – boson then decays into a beta particle and an process is equivalent to the process, in which a neutrino interacts with a neutron.

As can be seen from the figure, the weak interaction changes one. Weak Interaction Studies in Nuclear Beta Decay Table 1.

Beta radioactivity is the best known manifestation of the weak force.

It's a slow process as it occurs with difficulty. Unlike nuclear forces and electromagnetism, the weak force can transform a neutron into a proton or vice versa, thus changing the composition of a nucleus. Electron capture is sometimes included as a type of beta decay, because the basic nuclear process, mediated by the weak force, is the same.

In electron capture, an inner atomic electron is captured by a proton in the nucleus, transforming it into a neutron, and an electron neutrino is released.

A Lecture Notes Weak Interactions I 1 Nuclear β-decay The nuclear β-decay caused a great deal of anxiety among physicists. Both α- and γ-rays are emitted with discrete spectra, simply because of the energy conservation.

The energy of the emitted particle is the same as the difference between the initial and final state of the nucleus. Weak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun.

The weak interaction acts upon left-handed fermions—i.e., elementary particles with half-integer values of intrinsic angular. Alpha- Beta- and Gamma-Ray Spectroscopy Volume 1 offers a comprehensive account of radioactivity and related low-energy phenomena.

It summarizes progress in the field of alpha- beta- and gamma-ray spectroscopy, including the discovery of the non-conservation of parity, as well as new experimental methods that elucidate the processes of weak interactions in general and beta-decay Format: Ebook.The boson serves as an "interaction propagator" particle.

Namely it is short lived and serves as the "carrier" of the weak force that governs the beta decay. Similar cases are in the strong interactions where qluons play this role or in electromagnetism, where the .Nuclear and Particle Physics by Axel Maas.
