dc.descriptionWe investigate the distribution of clusters of galaxies and determine the cluster correlation function and power spectrum. Clusters of galaxies located in rich superclusters with at least 8 members form a quasiregular network of superclusters and voids. The correlation function of clusters in rich superclusters is oscillating with a period of 120 Mpc (for Hubble constant h=1), the power spectrum for the whole cluster sample has a peak at the corresponding wavelength. The power index on small wavelengths is n=-1.8, on large wavelengths the power index is within observational errors compatible with the Harrison-Zeldovich index n=1. The observed spectrum is compared with the spectrum of the standard CDM model, the probability that the observed spectrum is a random realisation of the CDM-type model is estimated to be not larger than one in million.
