Comment on "Structure and Hyperfine Parameters of E' Centers in alpha-quartz and Vitreous SiO2"
arXiv:cond-mat/9703027
Abstract
We point out that contrary to a recent suggestion by Boero et al. (PRL 78, 887 (1997)) the +1 charge state of the oxygen vacancy in alpha-quartz cannot be invoked as a candidate E' center in alpha-quartz and silica.
