Data on the \frac\ensuremathπ^\ensuremath-\ensuremathπ+ ratio in heavy-ion collisions are analyzed by theoretical formula. It accounts for Coulomb interaction between central charged fragment consisting of stopped nucleons with effective charge Zeff and charged \ensuremathπ's. The Coulomb wave function method is used in order to account for the finite \ensuremathπ production range \ensuremathβ. For the Gaussian source function it results in a quasiscaling in \ensuremathβ and Zeff, which makes determination of \ensuremathβ and Zeff difficult. Only sufficiently accurate data taken in the extreme small mT\ensuremath-m_\ensuremathπ region, where this quasiscaling is broken, could be used for this purpose.
