CHEMICAL DECOMPOSITION OF CRYSTALS OF LEAD IODIDE BY IRRADIATION IN AN ELECTRON BEAM
Journal Article

· Discussions Faraday Soc.
Thin crystals of lead iodide decompose in the beam of an electron microscope. The deconmposition was studied continuously by direct observation and by electron diffraction, for both low and high intensities of irradiation. The sequence of events follows a definite pattern, from a preliminary rearrangement of the microstructure, through an intermediate stage in which cavities are created inside the crystal, to the final stage in which metallic lead begins to precipitate. Cavity formation appears to be an important step toward final decomposition. The way in which cavities are formed by electron irradiation is not fully understood, but some tentative ideas, based on an ionization process, are put forward for discussion. (auth)
