Investigations were made of the pyroluminescence properties of barium
beta berate single crystals. The measurements were made at air pressur
es of 1-10 Pa and temperatures of 80-400 K. Luminescence was observed
as isolated flashes over the entire range of experimental conditions.
It was observed that the light flashes coincided with the pyrocurrent
oscillations. (C) 1998 American Institute of Physics. [S1063-7850(98)0
