In order to analyze data on charged pions correlation channels, π+(2π−) and π−(2π+), we propose new interferometry approach using the Coulomb wave function. We show that to describe adequately data we have to introduce new parameter describing the contribution of π−(k1)π+(k2)→π−(k2)π+(k1) process. Using this new formula we analyze data on π+(2π−) and π−(2π+) channels at s=91 GeV by DELPHI Collaboration, and estimate the magnitude of this new parameter as well as the degree of coherence.
