Abstract
We demonstrate the advantages of the wavelet analysis (WA) for resolving the structures in experimental data on e⁺e^- annihilation into hadron states with quantum numbers of meson. The WA yields a useful set of starting conditions for analysis of states with multiresonance unitary Breit-Wigner method. We also apply the WA for the ratio R_{e⁺ e^-} .
