Abstract

At COSY-Jülich the lifetime of very heavy hypernuclei, produced in the reactions induced by protons, was measured for non-mesonic Λ 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 A hyperon lifetime of (211 ± 30) ps was obtained in the p+U reactions and (160 ± 15) ps in the p+Bi reactions, respectively.
