Abstract
Positron annihilation and monochromatic illumination were used to determine the position in the band gap of the negatively charged state of the monova cancy in diamond. The association of the 488-nm absorption band (TH5) with divacancies was confirmed by positron annihilation, which additionally show ed that the divacancy has a negative charge state in the band gap.
