Explain the term nuclear isomers?

Answer»
  • The nuclides with the same number of protons (Z) and neutrons (N) or the same mass number (A) which differ in energy states are called nuclear isomers.
  • In this, the isomer of higher energy is said to be in the metastable state which is represented by writing “m” after the mass number.

e.g. Nuclear isomers of cobalt can be represented as, 60mCo and 60Co.
