We study the spatial correlations between two particles (or two holes) around a closed shell core in terms of the probability distribution expressed as a function of the c.m. coordinate R of the two particles and of their relative coordinate r. We find that the mixing of configurations induced by the pairing force leads to a probability distribution centered in regions corresponding to larger values of R and smaller values of r, as compared to the case of a pure (j)/sub 0//sup 2/ configuration. This tendency to a ''surface clustering'' is mainly due to the interference of the contributions coming from levels with different parity. However, even with the inclusion of a large number of configurations, the size of the localized ''cluster'' is much larger than that of a free dinucleon system.
