Answer: The nuclear equation is
.
Explanation:
A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.
For example, 
Here, energy is radiated in the form of gamma radiation.
Thus, we can conclude that the nuclear equation is
.
