摘要：

We have studied 80 events of candidates for XI-capture star at rest in nuclear emulsion, where XI- hyperons are produced in (K-, K+) reactions identified by a K+ spectrometer. The weak decay of heavy double hypernuclei is confirmed, studying the distribution of visible energy-release and the probability of emission of two fast protons, in comparison with those for single hypernuclei.
