Recently developed method of regularized analytic continuation (RAC) is applied to determination
of the 2Πg resonance of acetylene anion. The method is based on continuation of the electron
affinities calculated for the anion in presence of an external perturbation field. Its independence on the
correlation treatment of the many-electron system allows application of accurate coupled-clusters methods
for electronic structure calculations utilized in determination of the resonance position and width.
