| Popis: | With stationary electron nuclear double resonance (ENDOR) the two - pairs having trigonal and orthorhombic symmetry, respectively, and the trigonal - pair have been investigated. The hyperfine and quadrupole interactions with the interstitial and the acceptor nuclei and , respectively, have been determined with higher precision than possible with previous electron paramagnetic resonance (EPR) investigations. Also the interactions with several shells of neighbour nuclei around the pairs have been determined. For all three pair defects `negative' stationary ENDOR signals from and have been observed, where the saturation of the partially saturated EPR signal is enhanced upon induction of a nuclear magnetic transition in contrast to the usual positive stationary ENDOR signals where it is diminished. |
