Properties of the iota are explained by a radially mixed quarkonium state. Very different radial wave functions for the strange and nonstrange components arise from the near degeneracy of the first radially excited s overlines state and the second radially excited nonstrange state. The K overlineKπ decay is dominant; the ηππ decay suppressed and the SU(3) relation between the two decays naturally broken. Coherent effects analogous to those in nuclear giant resonances enhance production in radiative ψ decays by a considerable factor. One experimental test is a search for decays like D or F → ιπ → KoverlineKππ or ψ → ιø → π KoverlineKø .
