Archivio Istituzionale della RicercaAn experimental study of the K-stop(-) A -> Sigma(-) pA' reaction on A = Li-6, Li-7, Be-9, C-13, and O-16 p-shell nuclei is presented. The data were collected by the FINUDA spectrometer operating at the DA phi NE phi factory (LNF-INFN, Italy). Emission rates for the reaction in the mentioned nuclei are measured and compared with the few existing data. The spectra of several observables are discussed; indications of quasifree absorptions by a (np) pair embedded in the A nucleus can be obtained from the study of the missing mass distributions.

Abstract
An experimental study of the K-stop(-) A -> Sigma(-) pA' reaction on A = Li-6, Li-7, Be-9, C-13, and O-16 p-shell nuclei is presented. The data were collected by the FINUDA spectrometer operating at the DA phi NE phi factory (LNF-INFN, Italy). Emission rates for the reaction in the mentioned nuclei are measured and compared with the few existing data. The spectra of several observables are discussed; indications of quasifree absorptions by a (np) pair embedded in the A nucleus can be obtained from the study of the missing mass distributions.
