DECOMPOSITION OF CALCIUM FLUORIDE AND STRONTIUM FLUORIDE IN THE ELECTRON MICROSCOPE
Thin fragments of calcium fiuoride and strontium fluoride crystals were prepared that were suitable for examination by transmission electron microscopy. After a short irradiation by the electron beam, Moire patterns appear and these are attributed to the partiai decomposition of the fluorides, resulting in the formation of metallic calcium or strontium in a parallel orientation to the undecomposed fluorides. After further irradiation the patterns become diffuse and eventually disappear. (auth)
