Electron microscopic observation of alkali-halide crystals at low temperature

Electron microscopic studies on the coloration by X-rays (1), the additive colouration, and also the bleaching process (2) of some alkali-halide crystals were made only at room temperature until now. We also successively observed colouring and bleaching processes of the definite position of the same KC1 crystal by using two-stage replicas (3). The same kind of observations at liquid air temperature, howeve, is more important physically and practicable, after the replica technique at liquid air temperature has been studied in the meantime (4).
