Abstract

This study presents the results of a theoretical and experimental investigation of the process of positron annihilation in radiation capture centers (RCC) of quartz and quartz glasses irradiated byγ-rays. The value of the effective electron mass in the oxygen bridge atom vacancy (E′ center) is determined. This value proves to be larger than in the case of a quartz monocrystal and close to the value calculated from the optical absorption band of quartz glass (μ ∼ 5.0 me). It is shown that positron annihilation in [A1] centers is characterized by a greater half-width in the annihilation radiation angular correlation curve than in H-centers. The dependence of radiation capture center concentration on radiation dosage is obtained.
