Electron Spin Resonance in Neutron‐Irradiated Quartz

The electron spin resonance of one of the defects produced by fast neutron irradiation of crystalline quartz is analyzed. The g tensor and hyperfine tensors deduced from these results imply that the defect electron is in a nonbonding tetrahedral hybrid orbital on a silicon. It is suggested that the instability of the lattice at high doses results in part from the presence of these defects.
