Question

Which of the following process represents $\gamma$-decay?

• A. ${}_Z^{A}X{+}_0^{1}n{\to }_{Z-2}^{A-3}X+c$
• B. ${}_Z^{A}X{+}_{-1}e{\to }_{Z-1}^{A}X+g$
• C. ${}_Z^{A}X+r{\to }_{Z-1}^{A}X+a+b$
• D. ${}_Z^{A}X{\to }_Z^{A}X+\gamma$

Answer 1

Answer: (D)

${}_Z^{A}X{\to }_Z^{A}X+\gamma$

In a $\gamma$-decay, the values of A and Z do not change.

This condition is satisfied in option (d) only.
