Description

Phase-memory times TM for E'-centers in various quartz samples were measured by pulse-ESR. Manually ground quartz followed by γ-irradiation, α-irradiated quartz and that from a natural uranium deposit showed TM < 8μs indicating strong spin-spin interactions due to localized spins. Quartz glass and neutron-irradiated quartz showed longer TM of 15-18μs. Natural SiO2 with dense spins, (∼ 3.96 Ga) and sandstone from an impact crater were also examined. (author)
