    Results from a partial-wave analysis of the decay J/KS0K in the KS0K invariant-mass range 1.351.6 GeV/c2 are presented. Within the isobar model, the data in this mass range are best described by a mixture of 0-+ and 1++ amplitudes, corresponding to the K*K»+c.c (P wave), K*K»+c.c (S wave), and a0(980) (S wave) channels. These results show that (1430) is not a JPC=0-+ a0(980) resonance, but a mixture of overlapping states.
