| dc.description | Precise interaction matrices are reported for a boron-stabilized oxygenic-hole centre in x-irradiated zircon as derived from x-band electron paramagnetic resonance (EPR) measurements at ca 15 K. The presence of boron has been identified unequivocally through the observation and spin Hamiltonian analysis of superhyperfine structures from both naturally occurring isotopes of boron. Each of the parameter matrices indicates that the centre has point-group symmetry m (C<sub>s</sub> ), as is common in hole centres in zircon, where the hole centre is trapped on an oxygen atom within one of the crystal mirror planes. Analysis of the principal directions of these matrices indicates that the boron atom resides in a silicon position neighbouring the oxygenic electron vacancy. |
