Results from a partial-wave analysis of the decay {ital J}/{psi}{r arrow}{gamma}{ital K}{sub {ital S}}{sup 0}{ital K{plus minus}}{pi}{sup {minus plus}} in the {ital K}{sub {ital S}}{sup 0}{ital K}{sup {plus minus}}{pi}{sup {minus plus}} invariant-mass range 1.35--1.6 GeV/{ital c}{sup 2} are presented. Within the isobar model, the data in this mass range are best described by a mixture of 0{sup {minus}+} and 1{sup ++} amplitudes, corresponding to the {ital K}{sup *}{ital {bar K}}+c.c ({ital P} wave), {ital K}{sup *}{ital {bar K}}+c.c ({ital S} wave), and {ital a}{sub 0}(980) {pi} ({ital S} wave) channels. These results show that {eta}(1430) is not a {ital J}{sup {ital P}{ital C}}=0{sup {minus}+} {ital a}{sub 0}(980){pi} resonance, but a mixture of overlapping states.
