Abstract
At COSY-Julich the lifetime of very heavy hypernuclei, produced in the reac tions induced by protons, was measured for non-mesonic Lambda decay by the recoil shadow method. The measurements were performed at proton energies of 1.5 and 1.9 GeV and the background was determined at 1.0 GeV. The Lambda h yperon lifetime of (211 +/- 30) ps was obtained in the p+U reactions and (1 60 +/- 15) ps in the p+Bi reactions, respectively.
