| Abstract: | EPR studies of single crystal α-quartz at ca. 25 K, which had been X-irradiated, have revealed the presence of two new trapped-hole impurity centers. One of these is thought to be formed by trapping of an electron hole at an oxygen ion adjacent to a silicon 4+ ion vacancy occupied by four protons. The second center is similar with only three protons present. The Zeeman splitting (g) matrices for the two species have been determined and are compared to those for analogous aluminum hole species. |
