Question

Pick out the incorrect statement from the following

• A. $\beta$ Emission from the nucleus is always accompanied with a neutrino.
• B. The energy of the $\alpha$ particle emitted from a given nucleus is always constant.
• C. $\gamma$ - ray emission makes the nucleus more stable
• D. Nuclear force is charge independent.

Answer 1

Answer: (A)

$\beta$ Emission from the nucleus is always accompanied with a neutrino.

Answer 2

: $\beta^{-}$emission from the nucleus is always accompanied with an antineutrino.

The $\beta^{-}$decay is

$n \rightarrow p + \underset{electron}{e^{-}} + \underset{antineutrino}{\bar{\upsilon}}$
