The characteristics of BaF2 barium fluoride crystals, grown from the materi
als provided by manufacturers, were investigated. The parameters which are
important for application of the crystals in low-energy physics, electromag
netic high-energy, calorimeters for detecting gamma rays and electrons, and
measurement of energy in the maximum possible range from tens of MeV up to
hundreds of GeV as well as applications in medicine, instrument building,
geology and so on, were measured. 7 figures, 3 tables, 13 references.
