Question 63

Technetium-99m ( $99mTc^{99\text{m}}\text{Tc}$ ) is a metastable nuclear isomer widely used as a radioactive tracer in medical imaging. When a nucleus of $99mTc^{99\text{m}}\text{Tc}$ transitions to its ground state, $99Tc^{99}\text{Tc}$ , it undergoes gamma decay by emitting a high-energy photon.

State the change, if any, in the energy of the nucleus as a result of this transition.
