Nuclear Isomers
Nuclear isomers or excited states with the activation energy in keV related to the ground state.
The following table shows the atomic nuclei that are isotonic (same neutron number N = 130) and isobaric (same nucleon number A = 210) with Mercury-210. Naturally occurring isotopes are marked in green; light green = naturally occurring radionuclides.
