This paper reports on the scintillation properties of cylindrically shaped, {O}1 in. {times} 1 in., and 30 {times} 30 {times} 4.5 mm BaF{sub 2} crystals doped with 0.2, 0.3, 0.5, 0.8, and 1.0 mol% Ce{sup 3+} studied by means of X-ray and gamma ray excitation. Optical transmission, X-ray induced emission, and decay time spectra will be presented. The photoelectron (phe) yield/MeV was measured with an XP2020Q photomultiplier tube. The {O}1 in. {times} 1 in., 0.2 mol% doped crystal has a light yield of 1790 phe/MeV which is larger than the total light yield (1570 phe/MeV) of a pure BaF{sub 2} crystal of the same dimensions. The crystal shows two main scintillation decay times of 47 {plus minus} 5 ns and 260 {plus minus} 40 ns. For the 1.0 mol% doped crystal a light yield of 1210 {plus minus} 80 phe/MeV and a dominating decay time of 81 {plus minus} 7 ns were observed. The crystals scintillate at wavelengths larger than 300 nm and the scintillation light can be detected with glass windowed photomultiplier tubes.
