The two-pion contribution to the absorptive part of the forward nucleon-nucleon scattering amplitude in the unphysical region is calculated numerically in Cini-Fubini approximation. The magnitude of the contribution to the absorptive part from multi-pion (three and more-pion) intermediate states is evaluated from the relations used as sum rules and it is found that a resonance appears either in T=0, J=1, odd parity state (neutral vector boson) or in T=0, J=0, odd parity state (neutral pseudoscalar boson) or in both states of the multi-pion system. If the resonance is caused by a neutral vector boson with 3 pion-mass, the magnitude of the rationalized vector coupling constant is f^<v^2>/4π=1.2.
