The HypHI Phase 0 experiment with Li-6 projectiles at 2 A GeV on a carbon target has been performed at GS' in order to demonstrate the feasibility of precise hypernuclear spectroscopy with peripheral heavy ion collisions. Current data analyses have preliminary shown peaks in invariant mass distributions of p + pi(-) for Lambda, He-3 + pi(-) for H-3(Lambda) and He-4 + pi(-) for H-4(Lambda). Lifetime values for the corresponding peaks have been also deduced, which is in good agreement with the former known values. (C) 2012 Elsevier B.V. All rights reserved.
