摘要：

A hybrid-emulsion experiment has been carried out at KEK-PS to study S = -2 nuclei. With the analysis of about 35 % of total emulsion, we have successfully found three events of sequential weak decay of a double-hypernucleus. The results of these E373 events are summarized together with those of past experiments. The first experimental study of the branching ratios of weak decay modes of double-hypernuclei has been performed.
