Реферат:	eng: Diamond crystals synthesized in Mg-EuF2-C and Mg-EuF3-C systems using high PT (pressure-temperature) parameters are studied by electron paramagnetic resonance (EPR) and photoluminescence spectroscopy. The luminescence spectra of diamond crystals grown in europium containing systems have an optical center with a zero phonon line at lambda = 607 nm. The EPR spectrum of the diamond crystal grown in the Mg-EuF3-C system has a new paramagnetic center with hyperfine structure from a fluorine atom. This EPR spectrum is due to a C-3 nu (or D-3d) point symmetry center and is observed at low temperatures (T < 77 K). Various possible structures for the C-3 nu symmetry centers containing the Eu-F fragment are considered.
