Σ−pemission rates inK−absorptions at rest onLi6,Li7,Be9,C13, andO16

An experimental study of the ${K}_{\mathrm{stop}}^{\ensuremath{-}}A\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Sigma}}}^{\ensuremath{-}}p{A}^{\ensuremath{'}}$ reaction on $A=^{6}\mathrm{Li},\phantom{\rule{0.16em}{0ex}}^{7}\mathrm{Li},\phantom{\rule{0.16em}{0ex}}^{9}\mathrm{Be},\phantom{\rule{0.16em}{0ex}}^{13}\mathrm{C}$, and $^{16}\mathrm{O}\phantom{\rule{4pt}{0ex}}p$-shell nuclei is presented. The data were collected by the FINUDA spectrometer operating at the $\mathrm{DA}\mathrm{\ensuremath{\Phi}}\mathrm{NE}\phantom{\rule{4pt}{0ex}}\ensuremath{\phi}$ 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.
