Answer to Question #171019 in Physics for Jenna

Question

Using the conservation of baryon number, charge and lepton number, decide if the following reactions is possible:

a) n→p+e^- +Ve

Answer 1

The reaction

$$n→p+e^-+\nu_e$$

is not possible.

Charge numbers: (0) → (+e) + (-e) + (0) [conserved]

Baryon numbers: (1) → (1) + (0) + (0) [conserved]

Lepton numbers: (0) → (0) + (1) + (1) [not conserved]
