The treatment of the finite width and the inelastic effects previously proposed for the rho case is extended to the $omega$-phi case. This leads to a complex, and energy dependent $omega$-phi mixing formalism. Applications are done to computing rho, omega, and phi interference effects and their high energy tails in e$sup +$$e$$sup -$$Yields$$2$$pi$, 3$pi$, K anti K, $pi$$gamma$ and eta $gamma$. The possible existence of higher vector mesons is considered in an ideal nonet structure similar to the ordinary vector meson structure. Using SU$sub 3$ and the quark model relations, the coupling constants and width of the members of the first two nonets V' and V'' are predicted. Their effects (rho- rho' mixing included) are shown in the reactions e$sup +$$e$$sup -$$Yields$$2$$pi$, 3$pi$, K anti K, $pi$$gamma$ and eta $gamma$. The asymptotic behavior of the total cross section (e$sup +$$e$$sup -$$Yields$hadrons) is discussed in connection with the existence of the infinite series of vector mesons. The possibility of the limiting case where a strong mixing of many overlapping states occurs is emphasized. (FR)
