Query: $\Sigma^- p$ emission rates in $K^-$ absorptions at rest on $^6$Li,
  $^7$Li, $^{9}$Be, $^{13}$C and $^{16}$O   An experimental study of the $K^-_{stop}A\rightarrow \Sigma^- p A'$ 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 $\phi$-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 Quasi-Free
absorptions by a $(np)$ pair embedded in the $A$ nucleus can be obtained from
the study of the missing mass distributions.
