Аннотация:
A new centre formed by x-irradiation of a synthetic zircon crystal at 77 K has been found and studied by electron paramagnetic resonance at 10 K. The impurity ion is believed to occupy a substitutional site, as was the case for the earlier reported B centre. Interaction with an nucleus in a nearest-neighbour site lowers the site symmetry from (Laue class, 4/mmm) tetragonal to m (Laue class, 2/m) monoclinic.
