摘要：

The electron paramagnetic resonance (EPR) of β rhombohedral boron single crystals was investigated at 35 GHz and 300 K. It was found that the dark EPR signal is a superposition of several lines with anisotropic g factors and linewidths. A model is discussed using a special spin hamiltonian. We concluded that three of the lines are related to equivalent centres in the {100} planes. These centres must have an effective spin larger than 1 2. Two background lines are due to the carbon content in boron. © 1979.
