What is a neutrino ?

Text Solution

AI Generated Solution

### Step-by-Step Text Solution: 1. **Definition of Neutrino**: A neutrino is a type of subatomic particle that is a fundamental constituent of matter. It is classified as a lepton, which is a family of particles that also includes electrons and muons. 2. **Properties of Neutrinos**: - **Rest Mass**: Neutrinos have an extremely small rest mass, which is often considered to be negligible for many practical purposes. - **Charge**: Neutrinos carry no electric charge, meaning they are neutral particles. ...

The beta - decay process , discovered around 1900 , is basically the decay of a neutron n . In the laboratory , a proton p and an electron e^(bar) are observed as the decay product of neutron. Therefore considering the decay of neutron as a two- body decay process, it was predicted theoretically that the kinetic energy of the electron should be a constant . But experimentally , it was observed that the electron kinetic energy has continuous spectrum Considering a three- body decay process , i.e. n rarr p + e^(bar) + bar nu _(e) , around 1930 , Pauli explained the observed electron energy spectrum. Assuming the anti-neutrino (bar nu_(e)) to be massaless and possessing negligible energy , and the neutrino to be at rest , momentum and energy conservation principle are applied. From this calculation , the maximum kinetic energy of the electron is 0.8 xx 10^(6) eV The kinetic energy carried by the proton is only the recoil energy. What is the maximum energy of the anti-neutrino ?
