Question
Choose the correct nuclear process from the below options
[p : proton, n : neutron, ${{\rm{e}}^-}$ : electron, ${{\rm{e}}^+}$ : positron, v: neutrino, $\bar v$ : antineutrino]
Select the correct option:
A
${\rm{n}} \to {\rm{p}} + {{\rm{e}}^ - } + {\bf{v}}$
B
${\rm{n}} \to {\rm{p}} + {{\rm{e}}^ - } + \bar v$
C
${\rm{n}} \to {\rm{p}} + {{\rm{e}}^ + } + v$
D
${\rm{n}} \to {\rm{p}} + {{\rm{e}}^ + } + \bar v$
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Theoretical equation for ${\beta ^{ - 1}}{\rm{ decay }}$ ${\rm{n}}_0^1 \to {\rm{p}}_1^1 + {\rm{e}}_{ - 1}^{ - 0} + \overline {\rm{v}} $
