| metastable | 1. Of uncertain stability; in a condition to pass into another phase when slightly disturbed; e.g., water, when cooled below the freezing point may remain liquid but will at once congeal if a piece of ice is added. 2. Denoting the excited condition of the nucleus of a radionuclide isomer that reaches a lower energy state by the process of isomeric transition decay without changing its atomic number or weight; e.g., 99m99mTc → 9999Tc + g.

| metastable s. |
1. an excited state with an unusually long lifetime, ranging from 10-6 second to several minutes. 2. an intermediate state between the ground and excited states, requiring additional energy before decay to the ground state can occur.
