A hybrid emulsion experiment was carried out to study double-strangeness nuclei produced via ξ- hyperon capture at rest with the expectation of ten times larger statistics than previous experiments. We have analyzed 5% of the total emulsion and found one "twin-hypernuclei" event involving the emission of two single-λ hypernuclei and a nuclear fragment from a ξ- hyperon stopping point. The event is interpreted as the decay of a ξ- + 14N atomic system to λ/5 He + λ/5 He + 4 He + neutron. The species of the ξ- -atom and the fragmentation products are uniquely identified for the first time for twin-hypernuclei events. Combined with the results from a past hybrid-emulsion experiment, one double-λ hypernucleus and three twin-hypernuclei events have been found from ξ- captures on light emulsion nuclei. The ratio of the detected rate of double-λ hypernuclei to that of twin-hypernuclei is compared with theoretical estimates.
