Question 163 of 239

Choose the correct nuclear process from the below options
[p: proton, n : neutron, e−\mathrm{e}^{-}: electron, e+\mathrm{e}^{+}: positron, v:v: neutrino, vˉ\bar{v} : antineutrino]

Show answer and solution

Answer: (D) n→p+e−+vˉ\mathrm{n} \rightarrow \mathrm{p}+\mathrm{e}^{-}+\bar{v}

For all nuclear processes, charge must be conserved. Also, when a release of an electron ( e−e^{-}) is always accompanied by a release of an antineutrino ( vˉ\bar{v} )

Hence, n→p+e−+v‾n \rightarrow p+\mathrm{e}^{-}+\overline{\mathrm{v}} is the correct answer.
