An experimental study of the Kstop-A→Σ-pA′ reaction on A=Li6,Li7,Be9,C13, and O16p-shell nuclei is presented. The data were collected by the FINUDA spectrometer operating at the DAΦNEφ 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.
