    The muon is a heavy unstable version of the electron, with mass mm= MeV/c2 and lifetime tm ~ msec. The decay m g e ne nm, or "muon beta decay" is one . Beta Decay. Beta decay is one process that unstable atoms can use to become more stable. There are two types of beta decay, beta-minus and beta-plus. During beta-minus decay, a neutron in an atom's nucleus turns into a proton, an electron and an antineutrino. The electron and antineutrino fly away from the nucleus, which now has one more proton.

Beta plus decay is the transformation of a proton into a neutron, with emission a positron and a neutrino. This is the weak nuclear force that is responsible for the decay of a neutron into a proton or a proton into a neutron without changing the number of nucleons.

Nucleons are composed of up quarks and down quarks, and the weak force allows a quark to change its flavour by emission of a W boson leading to creation of an electron/antineutrino or positron/neutrino pair.

For example, a neutron, composed. Effects of Weak Interactions. (Book Reviews: Beta Decay and Muon Capture)Author: Barry R. Holstein. Muon capture is the capture of a negative muon by a proton, usually resulting in production of a neutron and a neutrino, and sometimes a gamma photon.

Muon capture by heavy nuclei often leads to emission of particles; most often neutrons, but charged particles can be emitted as well. Ordinary muon capture (OMC) involves capture of a negative muon from the atomic orbital without emission of a. Probing double beta decay by nuclear muon capture M.

The muon is an unstable subatomic particle with a mean lifetime of μs, much longer than many other subatomic with the decay of the non-elementary neutron (with a lifetime around 15 minutes), muon decay is slow (by subatomic standards) because the decay is mediated only by the weak interaction (rather than the more powerful strong interaction or electromagnetic interaction Discovered: Carl D.

Anderson, Seth Neddermeyer (). Gamma-rays following nuclear capture of negative muons in enriched 48Ti, 76Se, Cd, as well as natural Se and Cd targets were measured. Time evolution of several gamma-lines allowed to deduce the total μ-capture rates in Ti, Se and Cd isotopes, which are compared to the Primakoff estimate.

The data on the partial μ-capture rates will be used for more precise calculation of the 2β-NMEs of Cited by: 6. We made extensive investigations on the weak charged nucleon currents and structure of complex nuclei in weak nuclear processes.

Muon decay is somewhat similar to beta decay. Following the weak interaction, it decays (via a W intermediate vector boson, IVB) into a muo-neutrino and a pair of electron and an anti-electron neutrino.

Here is a Feynman diagram for the decay. Mor. muon capture evaluated the capture strength via observation of nuclear gamma rays and X-rays. We used the enriched molybdenum thin lm in our rst measurement at. The muon capture process (mu /sup -/ + p yields n + nu) is discussed.

and an experiment is described in which muon capture rates were measured to accuracies of a few per cent for various target nuclei. 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 nuclear physics, beta decay is a type of radioactive decay in which a beta ray (fast energetic electron or positron) and a neutrino are emitted from an atomic nucleus.

Precision {beta} decay experiments represent an important and complimentary approach to high-energy searches for physics outside the ''Standard Model'', our current understanding of fundamental particles and their interactions. The mirror decay of {sup 37}K provides an .The weak interaction is responsible for radioactive decay, including the above Beta-minus decay.

to decay without neutrinos it was realized that the force was more complex than had been posited in Fermi's theory of beta decay. that it is an antineutrino that accompanies the electron in β decay.

When the decay or capture of a muon.During beta decay, an atom's nucleus sheds excess energy by converting a neutron into a proton and an electron and, as scientists now know, an antineutrino. Scientists noticed that when atoms of a particular isotope underwent beta decay, they always lost the same amount of energy, but the electrons were ejected with a range of energies.
