Explain fermi theory of beta decay
Answers
Fermi theory of Beta decay or Fermi's interaction was proposed by Erico Fermi in 1933.
This interaction was given to explain the decaying of a neutron by direct coupling of a Neutron with a Electron. The beta decay of a neutron transforms into a proton and neither the beta particle nor its associated neutrino exist within the nucleus prior to the beta decay, but these are created in the beta decaying process.
The probability of nuclide decaying due to beta and other forms of decay is determined by its nuclear binding energy.
Beta decay is caused due to weak force, which is characterized by relatively lengthy decay times.
Electron capture us also considered as a type of beta decay because the basic nucleya process which is mediated by the weak force is same in the electron capture.
In this process of electron capture and inner electron is captured by a Proton in the nucleus and is transformed into a neutron resulting in the release of an electron neutrino.
