Abstract

An analysis is presented of 6658 events of the reaction ..pi../sup -/p ..-->.. phi phi n at 22 GeV/c. This data is well represented by three resonances, all with quantum numbers I/sup G/J/sup PC/ = 0/sup +/2/sup + +/. In a second analysis, which consists of 40494 new events of the reaction ..pi../sup -/p ..-->.. K/sub s//sup 0/K/sub s//sup 0/n at 22 GeV/c, we obtain the S/sub 0/, D/sub 0/ and G/sub 0/ Argand amplitudes for ..pi pi.. ..-->.. K anti K. The theta (1690) is shown to decay into ..pi pi.. by less than 4% and only is required in J/psi radiative decay experiments.
