Hypernuclear spectroscopy with K− at rest on 7Li, 9Be, 13C and 16O

The FINUDA experiment collected data to study the production of hypernuclei on different nuclear targets. The hypernucleus formation occurred through the strangeness-exchange reaction Kstop−+ZA→ZΛA+π−. From the analysis of the momentum of the emerging π−, binding energies and formation probabilities of LiΛ7, BeΛ9, CΛ13 and OΛ16 have been measured and are here presented. The behavior of the formation probability as a function of the atomic mass number A is also discussed.
