Abstract
The production of very heavy hypernuclei has been investigated at COSY Julich in the interaction of protons of 1.0 GeV. 1.5 GeV and 1.9 GeV with bismuth and uranium, Identification was based on the detection of fragments from Lambda delayed fission using a recoil-shadow technique which yielded cross sections for production and fission decay of hype rnuclei of about 5 mu b (Bi target) and 20 +/-4(stat.)(-8)(+13)(syst.) mu b (U target). A lifetime of 240 +/- 45(stat.) +/-(syst.) ps has bee n deduced for the uranium target from the position distribution of fis sion fragments.
