AB  - We propose the reaction psi(3686)->Xi<overline>+K-<overline>0 Sigma(& lowast;-), with the Sigma(& lowast;-) decaying to pi(-)Lambda in order to show evidence for the existence of two Xi(1820) states, one around 1824 MeV and narrow, and another one around 1875 MeV and wide. The phase space for K<overline>0 Sigma(& lowast;-) production reduces the effect of the lower mass resonance, magnifying the effect of the higher mass resonance that shows clearly over the phase space. The estimated rate of the production is bigger than the one of the psi(3686)->Xi<overline>+K-Lambda reaction, where a clear peak for Xi(1820) was observed by the BESIII collaboration, what makes the Beijing facility ideal to carry out the reaction proposed.
