Rv. Mehta et al., AN EXAMINATION OF THE RELATIONSHIP BETWEEN CRYSTAL SHAPE AND STRUCTURAL FEATURES OF SILVER-HALIDE TABULAR CRYSTALS, Journal of imaging science and technology, 39(1), 1995, pp. 67-69
It has been hypothesized for a long time that the shape of a tabular c
rystal depends upon whether there are an even or odd number of twin pl
anes or on the location of twin planes relative to the tabular faces.
Transmission electron microscopy on cryosections of a pair of high-asp
ect-ratio silver halide tabular emulsions reveals that the suspected c
orrelations do not exist. The explanation based on the recently propos
ed cube-octahedral model needs further consideration now.
