• We propose a new method for the Coulomb wave function correction including the momentum resolution for charged hadron pairs and apply it to the precise data on πz π{ correlations obtained in p + Ta reaction at 70 GeV/c. It is found that interaction regions of this reaction (assuming Gaussian source function) are 5.6 ± 3.0 and 4.4 ± 2.6 fm for the thicknesses of the target 8 and 1.4 microns, respectively. The physical picture of the source size obtained in this way is discussed.
