The detection of X defect as a direct result of irradiation is reported. TSC experiments performed before and after annealing, at temperatures higher than 200C, revealed the existance of a donor state of the X defect. During annealing at high temperatures the formation of X defect overpass 5 times the concentration of divacancies. Thus, an identification of the X center with V2O defect, via V2+O reaction, becomes doubtfull while its identification with V2O2 ,via V2+O2d and VO+VO reactions, proved to be well suported by experiments and simulations.
