"Subthreshold" defect formation in natural diamond
Zaitsev A.M. , Vavilov V.S. , Gippius A.A.
Occurrence of vacancies in diamond under bombardment by electrons with energies lower than the threshold energy for elastic discomposition is observed by the cathodoluminescence method. It is suggested that the vacancies develop as a result of decay of unstable ion configurations that include multiply ionized atoms of transition metals.
