Which of following reaction is correct? (Where symbols have their usual meanings) (1) n → p + e^- + v

Question

Which of following reaction is correct? (Where symbols have their usual meanings)

(1) \(n \rightarrow p + e^ – + v\)

(2) \(n → p + e ^+ + v\)

(3) \(n → p + e ^+ + \bar v\)

(4) \(n → p + e ^– + \bar v\)

Answer 1

Correct option is : (4) \(n → p + e ^– + \bar v\) 

In 2, 3 charge conservation is not holding and in neutron decay, antineutrino \((\bar v)\) is released.
