Abstract: The tetragonal (D-2d symmetry) Si-B3 defect is intensively observed by electron spin resonance (ESR) in neutron-irradiated Cz-grown c-Si after annealing in the range 250-500degreesC. In addition to the limited known one, a rich Si-29 hyperfine structure is revealed and fully angularly mapped. Spectra simulations show that the defect unpaired electron has its strongest hf interaction with two equivalent Si sites in the first shell, a next interaction with four equivalent Si sites in the second shell, and a last interaction with eight equivalent Si sites in the third shell. From comparison of the data with extensive theoretical calculations on the tetrainterstitial (I-4), the Si-B3 is identified as the I-4 defect.
