We are testing the applicability of the algebraic procedure developed by Richardson for bound states to solvethe pairing-force problem in presence of states with complex energies. This scenario, in which nucleons occupysingle-particle states with complex energies and interact via the pairing force, is closely related to the microscopicdescription of nuclei with a large neutron (or proton) excess in basis which includes single-particle resonances.It is shown that the method gives results which are in good agreement with exact solutions. This finding is incoincidence with previously published works, by other authors, based on different methods to describe resonances.
