摘要：

The binding energies of the Me+' and Re+' centres (i.e. systems comprising a positron trapped by negatively charged M' or R' colour centres) are calculated using the model of two non-interacting particles localised in the field of two or three delta potentials. The results presented for NaF, NaCl, KCl, and KBr and KI crystals show an increase in the binding energy in the sequence Fe+', Me+' and Re+' centres.
