| dc.description | An interaction between two heavy electrons mediated by two light electrons is investigated within the asymmetric Hubbard model on a square cluster with sites. The pair correlation function describing the probabilities of all relative positions of the heavy electrons is calculated by an approximative method. An effective attraction is found to exist in a certain range of model parameters. |
