High School What is the meaning of decay mode IT in nuclear physics ?

Click For Summary
Isomeric Transition (IT) in nuclear physics refers to the decay of a long-lived nuclear isomer through gamma emission or internal conversion. This process involves an excited state of a nucleus that possesses an unusually long half-life. A notable example is Technetium-99m (Tc99m), which has a half-life of 6.02 hours and an energy of 0.141 MeV. The "m" in Tc99m indicates its metastable state. Understanding IT is essential for applications in nuclear medicine and radiopharmaceuticals.

Could you point out an example for us ?

IT = Isomeric Transition. It indicates decay of a long lived nuclear state (an isomer) via a gamma or internal conversion.

IT refers to isomeric transition. It is the decay of a nuclear isomer an excited state of a nucleus that has an unusually long half -life. A great example is Tc99m in which the first excited state of Tc99 has an energy of 0.141 MeV and a half-life of 6.02 hrs. The m stands for metastable.
