Question

Neutron decay in the free space is given as follows:
${}_0{n}^1{\to }_1{H}^1{+}_{-1}{e}^0+\left[\right]$
Then, the parenthesis represents

• A. photon
• B. graviton
• C. neutrino
• D. antineutrino

Answer 1

The correct option is D antineutrino

Antineutrinos are the antiparticles of neutrinos, which are neutral particles produced in nuclear beta decay. These are emitted during beta particle emissions, in which a neutron decays into a proton, electron, and antineutrino. They have a spin of , and are part of the lepton family of particles.
