Nuclide Chart half-life in MEV?

what is the meaning of MEV in the column of half-lives? (even if it would be MeV  ... with lower case "e" I would not understand the meaning of an energy as a  half-life-related quantity!

For very short lived nuclides, the energy value is the level width,
  half life = ln 2 hbar / MeV
By uncertainty princliple.
