已经研究了从气相沉积到氯化钠基底上的银的成核速率作为基底温度和发生率的函数。这些实验是在超高真空系统中在原位切割的基底上进行的。结果发现与之前出版物中提出的成核过程模型一致。利用该理论，得到银在氯化钠上的吸附能为0.4 eV。据估计，表面扩散的活化能小于0.2 eV，并且临界核在所采用的较低过饱和度下的解离能为2.1 eV。
The nucleation rate of silver deposited from the vapor phase onto a sodium chloride substrate has been studied as a function of substrate temperature and incidence rate. The experiments have been performed in an ultra‐high‐vacuum system on a substrate cleaved in situ. The results are found to be in agreement with a model of the nucleation process suggested in previous publications. Using the theory, a value of 0.4 eV has been obtained for the adsorption energy of silver on sodium chloride. It is also estimated that the activation energy for surface diffusion is less than 0.2 eV, and that the dissociation energy of the critical nucleus at the lower supersaturations employed is 2.1 eV.
