The behaviour of radiation induced carbon related defects in high resistivity silicon detectors has been investigated. The defects were introduced by alpha-particle irradiation and the measurements were carried out by the DLTS-technique. The unusual defect behaviour consists in low temperature anealing, including self annealing at room temperature, of the interstitial carbon Ci with a simultaneous increase of the (Ci-Oi)-complex concentration. The kinetic parameters of the process have been determined from the increase of the Ci-centre concentration versus time. Tho annealing velocities have been observed, which ar due to different heat treatments during the detector fabrication process.
