We have evaluated the mechanism analogous to pion absorption which contributes to the pion double-charge-exchange amplitude leading to double isobar analog states. We find appreciable corrections at low energies around T=50 MeV. Around the resonance region the corrections are small and the most visible effect is a small shift of the minimum to smaller angles, which is however not big enough to reproduce the experimental data.
