Q.
Which of the following processes represents a $γ$ -decay [2002]

1 ${}^{A}X_{Z} + γ ⟶ {}^{A}{X_{Z - 1} + a + b}$

2 ${}^{A}X_{Z} + {}^{1}n_{0} ⟶ {}^{A - 3}X_{Z - 2} + c$

3 ${}^{A}X_{Z} ⟶ {}^{A}X_{Z} + f$

4 ${}^{A}X_{Z} + {}^{0}e_{- 1} ⟶ {}^{A}{X_{Z - 1} + g}$

Ans.
(3)

In $γ$ -decay, the atomic number (Z) and mass number (A) do not change.
