We present model independent high resolution amplitude analyses of CERN dataon pi(-)p->pi(-)pi(+)n at 17.2 GeV/c for dipion masses 580-1080 MeV at smallmomentum transfers on polarized target (Analysis I) and unpolarized target(Analysis II). The results for S- and P-wave transversity amplitudes from theAnalysis I are used in a model independent determination of helicityamplitudes. All three analyses provide similar evidence for rho^0(770)-f_0(980)mixing in S- and P-wave amplitudes. In Analyses I and II the S-wave amplitudes|S_d|^2 peak at rho^0(770) mass while the P-wave amplitudes |L_d|^2 dip atf_0(980) mass. In both analyses the S-wave amplitudes S_tau are nearly in phasewith amplitudes L_tau for both transversitities tau=u(spin up) and d(spindown), indicating resonant phases of rho^0(770) also in the S-wave. The S-wavesingle flip amplitudes |S_1|^2 and the relative phases Phi(S_1)-Phi(L_1) showthe same pattern. While the non-flip amplitudes |L_0|^2 are small below 960MeV, there is a sudden rise above this mass that may reflect the presence off_0(980) resonance. We show that the apparent dependence of rho^0(770) width onhelicity in amplitudes |U_tau|^2 and |N_tau|^2 results from the interference ofamplitudes with helicities lambda=+/-1 and not from the violation ofrotational/Lorentz symmetry. This suggests that the production mechanism andthe mechanism responsible for rho^0(770)-f_0(980) mixing have independentdynamical origins.
