Mott Published 21 January 1938 Physics Proceedings of The Royal Society A: Mathematical, Physical and Engineering Sciences Webimage was a silver cluster, and Gurney & Mott (I 938) have presented a dynamical theory of the processes occurring. According to this theory, the absorption of light produces electrons and holes in the conduction and valence bands respectively of the silver halide. The photoelectrons spend some time in shallow traps, which are
