Question

can we say that anti-neutrino particles help in the emission of Beta rays?​

Answer 1

Answer:

The neutrino

The neutrino plays an essential role in the models of elementary particles and in the theory of the formation and development of the universe. The existence of the neutrino was predicted by Pauli in 1927 but it was not proven until 1956 when Reines and Cowan detected them in experiments at the Savannah River (USA) nuclear reactor. Since elementary particles and in the theory of the formation and development of the universe. The existence of the neutrino was predicted by Pauli in 1927 but it was not proven until 1956 when Reines and Cowan detected them in experiments at the Savannah River (USA) nuclear reactor. Since neutrinos are emitted in the β-decays following fission, nuclear reactors are the most intense neutrino sources on earth. The detector in the discovery experiments consisted of a scintillating solution containing cadmium surrounded by photomultipliers to observe the scintillations which occurred as a consequence of the following reactions:

The γ's emitted are of different energy; the γ much higher. There is also a time lag between the γ's because of the time required for the fast neutrons to be slowed down to thermal energy. The detection system allowed a delay time to ascertain a relation between γ

Since the 1950s it has become clear that neutrinos exist as several types. In β− decay an “anti-neutrino” is formed, while a “neutrino” is emitted in β+ decay. Both these neutrinos are now referred to as electron neutrinos, and ve, respectively.

The pions formed in nuclear particle reactions are unstable and decay with a life-time of 3 × 10−8 s into a muon and a µ neutrino:

The mass of the muon is 0.1135 u (105.7 MeV). The muon is also unstable and has a life-time of 2 × 10−6 s; it decays into an electron, an e neutrino and a µ anti-neutrino:
