Abstract

Evaluation of contributions from dispersion integrals to the real part of forwardπHe4 scattering amplitude is reconsidered. By application of a generalized mean-value theorem to the dispersion integral from the lowest branch point to the elastic threshold, a model-independent conclusion on the imaginary part of forwardπHe4 scattering amplitude in unphysical region is drawn.
