The lattice constant of evaporated KCl-crystals was measured with an accuracy of 0.01% using gold foil as a standard. The lattice constant of gold foil was calibrated in terrns of TlCl and was found in agreement with the X-ray value. Spacings of KCl measured just after evaporation are larger than the X-ray value by about 0.15%, provided the size of KCl-crystals are larger than 150Å. Spacings decrease when evaporated specimens are exposed to the air or are heated in vacuum. The lowest value of lattice constant obtained in this experiment is in agreement with the X-ray value within the experimental error.
