臭化銀に於る感光銀の方位配列 (第1報)

抄録

Various orientations of photolytic silver were examined by the electron diffraction method and discussed of their origins. Some orientations were attributed to the aggregation of interstitial silver ions. The other orientation, Which was found just beneath the surface was due to Fcenters. The former contains parallel orientation and Berry's orientation, and the latter was (100) orientation of silver on (111) innerface of silver bromide. In the course of photolysis, intermidiate crystal was also found, which showed cubic system having the lattice constant of 6.55 A. The activation energy of interstitial silver ion alone was calculated as about 0.5 eV from the time rate of photolysis of excess silver ion with temperature.
