Results of a high-statistics study of elastic scattering and meson resonances produced by -p interactions at 8 GeV/c are presented. Large statistics and small systematic errors permit examination of the complete kinematic region. Total differential cross sections are given for 0,-, f0, g0, -, 0, and N* resonances. Spin-density matrix elements and Legendre-polynomial moments are given for f resonances. The results for 0 and f0 resonances are compared with the predictions of a Regge-pole-exchange model. Properties of the above resonances are compared and discussed. In particular, we present evidence that the 0 and f0 production mechanisms are similar. The similarity of the g0 t distribution to that of the 0 and f0 suggests a common production mechanism for all three resonances.
