Abstract

We have studied stars in nuclear emulsion due to the capture at rest of the Ξ- hyperons produced in the (K-, K+) reaction. The sequential weak decay of a double hypernucleus (nucleus with S = -2) has been directly observed. The double hypernucleus is assigned as either 10ΛΛBe or 13ΛΛB. This assignme...
