Positron annihilation in BaF2 crystals
- 1. Thessaloniki Univ. (Greece). Dept. of Nuclear Physics
Description
Positron lifetime measurements in BaF2 were performed in the temperature range 10 to 292 K. Three lifetime components were resolved, the third component having a very low intensity. The intensity of the second component increases between 12 and 80 K. For further increase of the temperature, up to 290 K, the intensity of this component falls from about 63% to 37%. An increased positronium formation probability is suggested for explaining this observation. Some alternative explanations are discussed, as well. (author)
