The E885 collaboration utilized the 1.8 GeV/c K- beam line at the AGS to accumulate greater than 10 times the world's existing data sample of (K-,K+) events on carbon. The data were used to search for signatures of the production of Ξ hypernuclei, double-Λ hypernuclei, and H Dibaryons. Evidence for the creation of 12ΞBe is seen. Reasonable agreement between the data and theory is achieved by assuming a Ξ-nucleus Wood-Saxon potential well depth, V0Ξ, of about 14 MeV. Upper limits for the production of double-Λ hypernuclei are presented. Upper limits for H-Dibaryon production are presented which are a factor of 50 below calculated rates.
