摘要：

We report the first observation of the Xi(-) pi(+) scattering mode of the Xi(0)(1690); confirming the existence of this resonance. The Xi(0)(1690) were produced by Sigma(-) of 345 GeV/e mean momentum of copper and carbon targets. The mass and width are close to those observed earlier for the Xi(-)(1690) in the Lambda K- decay channel. The product of inclusive production cross section and branching ratio is given relative to that of the Xi(0)(1530).
