Hypernuclear spectroscopy with K${}^{-}$ at rest on ${}^7$Li, ${}^9$Be, ${}^{13}$C and ${}^{16}$O

Abstract

The FINUDA experiment collected data to study the production of hypernuclei on different nuclear targets. The hypernucleus formation occurred through the strangeness-exchange reaction $K_{stop}^{-}+{}^{A}Z\to {}_{\hat{I}}^A›Z+\ddot{I}{€}^{-}$. From the analysis of the momentum of the emerging $\ddot{I}{€}^{-}$, binding energies and formation probabilities of ${}_{\hat{I}}^7›$Li, ${}_{\hat{I}}^9›$Be, ${}_{\hat{I}}^{13}›$C and ${}_{\hat{I}}^{16}›$O 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.
