${\Sigma }^{-}p$ emission rates in $K^{-}$ absorptions at rest on ${}^6$Li, ${}^7$Li, ${}^9$Be, ${}^{13}$C and ${}^{16}$O

Abstract

An experimental study of the $K_{stop}^{-}A\to {\Sigma }^{-}p{A}^{\prime }$ reaction on $A{=}^6$Li, ${}^7$Li, ${}^9$Be, ${}^{13}$C and ${}^{16}$O $p$-shell nuclei is presented. The data were collected by the FINUDA spectrometer operating at the DA$\Phi$NE $\varphi$-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 Quasi-Free absorptions by a $(np)$ pair embedded in the $A$ nucleus can be obtained from the study of the missing mass distributions.
