| Research Abstract |
Photoluminescence (184-240 nm) of BaF_2 has been investigated with use of an intense undulatory radiation from the UVSOR ring as a pumping source. It is found that the emission intensity is enhanced and the decay time becomes fast when a mirror is adjusted for best collimation. These facts suggest a possibility of the light amplification due to a population inversion between the valence and outermost-core bands.
