Abstract
The statistical analysis of a distribution of 2 D nucleation sites on single crystal silver microelectrodes has been carried out on a collection of experimental potentiostatic current-time transients of single nucleus growth. The transients were interpreted in terms of a geometric model for the growth of a circular nucleus on a circular electrode. It was found that the geometric model is an adequate one for interpreting the experimental data. The locations of the nucleation sites were determined from the shape of the current-time transients. There is quantitative evidence that about 24% of the total number of nuclei originated on preferred sites or active centres. Some preliminary results from an autocorrelation analysis are also presented.
