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 View K-(stop) + A,Z --> Lambda-A,Z +pi-. From the analysis of the momentum of the emerging pi−, binding energies and formation probabilities of Lambda-7Li, Lambda-9Be, Lambda-13C and Lambda-16O 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.
