Question

Antineutrino can be detected during the emission of :

• A. $\alpha$-rays
• B. $\beta$-particles
• C. protons
• D. X-rays

Answer 1

The correct option is B $\beta$-particles

As we know,
when an neutron decays, it forms proton, beta particles and antineutrino
${}_0^{1}n{⟶}_{+1}^{1}p{+}_{-1}^{0}e+\overline{v}\left(\overline{v}isantineutrino\right))$
neutron proton beta particles antineutrino
