    Which of the following process represents a Y - decay?

    A)  \[^{A}{{X}_{Z}}+\gamma {{\to }^{A}}{{X}_{Z-1}}+a+b\]

    B)  \[^{A}{{X}_{Z}}{{+}^{1}}{{n}_{0}}{{\to }^{-3}}{{X}_{Z-2}}+c\]

    C)  \[^{A}{{X}_{Z}}{{\to }^{A}}{{X}_{Z}}+\gamma \]

    D)  \[^{A}{{X}_{Z}}{{+}_{-1}}{{e}^{0}}{{\to }^{A}}{{X}_{Z-1}}+g\]

    Correct Answer: C

    Solution :

    In \[\gamma \] - decay, the atomic number (Z) and mass number [A] does not change. So the correct option is [C] because in all other options either Z or A or both is changing.
