摘要：

Mossbauer measurements were performed on GaAs implanted with Te-129m-isotopes. A defect configuration is observed which is characterized by a large electric field gradient. This defect configuration shows persistent photoionisation and it is associated with the so-called "DX-center". The time constant of the relaxation from the substitutional donor-site to the DX-center defect site is measured.
