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