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

[HemKo]

I showed beta decay in decay mode of Nuclear chart..but I couldn't find what is the meaning if IT 100%..

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 Tc^99m 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.
