摘要：
A study was made of the electroabsorption in the spectral range 2. 82 - 2. 92 ev which was attributed to excitons bound to neutral boron. It was established that the band excitons experienced strong internal electric fields. These fields were created by the centers to which excitons were found. This led to the conclusions that the centers were donor-acceptor dipoles and not point centers as assumed earlier.
