Experimental studies of the effects of Y*/sup 0/ production in the absorption of K/sup -/ mesons at rest and in flight in complex nuclei in nuclear emulsions concluded that the existence of Y*/sup 0/ yields SIGMA /sup s + pi /sup s was established, the mass of Y*/sup 0/ >s greater than the mass of Y*/sup s by 10 to 15 Mev, the width of the half maximum resonance should be less than 40 Mev, and about 1/3 of all SIGMA /sup s + pi /sup s production in K/sup -/ absorption by emulsion proceed by the Y* channel. Suggestions are made concerning the possibility that the multi-nucleon K/sup -/ captures at rest are produced by a two-step process through Y*: K/sup -/ + N (bound) yields Y* and Y* + nucleon yields hyperonnucleon.
