Question

In the $\beta^{+}$ decay, the particle emitted along with neutron and positron is

• A. Electron
• B. Proton
• C. Neutrino
• D. Anti-neutrino

Hint:

β\textsuperscript{+}: p → n + e\textsuperscript{+} + ν{e}; β\textsuperscript{−}: n → p + e\textsuperscript{−} + \={ν}{e}.

Answer 1

The Correct Option is C

• In $\beta^{+}$ decay (positron emission) a proton converts to a neutron, releasing a positron and a neutrino (specifically an electron neutrino, $\nu_e$).
• $\beta^{-}$ decay emits an electron and an anti-neutrino.
• Hence the correct answer is (3) Neutrino.
