A new paramagnetic center was produced by 550-kV electrons in hexagonal boron nitride. It is shown that this center is a three-boron center and consists of an electron trapped in a nitrogen-ion vacancy (F center). The hyperfine interaction was found to be anisotropic with A_{perpendicular} = 40.0 +- 0.5 G and A_parallel = 45.3 +- 0.5 G for the interaction with ¹¹B nuclei. The g factor was found to be g = 2.0020 +- 0.0008. The thermal stability of this center was investigated.
