摘要：

When irradiated nitrogen-rich natural diamond is heated isothermally, the vacancies are destroyed at two rates. In both processes vacancies migrate to and are trapped at the nitrogen. The faster process coincides with a sharpening of the optical transitions of the vacancy. Both processes have the same activation energy of E(m) = 2.3 +/- 0.2 eV By annealing nitrogen-free diamond, E(m) is shown to be the migration energy of the neutral charge state of the vacancy.
