JEE Main 2025 — 28 January, Morning Shift — Question 60

Choose the correct nuclear process from the below options

[ p : proton, n : neutron, e−e^-: electron, e+e^+: positron, vv : neutrino, νˉ\bar{\nu} : antineutrino]

  1. Option A:

    n→p+e−+vˉn \rightarrow p+e^{-}+\bar{v}

    Correct
  2. Option B:

    n→p+e−+vn \rightarrow p+e^{-}+v

  3. Option C:

    n→p+e++vˉ\mathrm{n} \rightarrow \mathrm{p}+\mathrm{e}^{+}+\bar{v}

  4. Option D:

    n→p+e++vn \rightarrow p+e^{+}+v

Answer: A
