Observable sensitivities to scaling of K +-nucleon interactions within nuclei

We have used an impulse approximation optical model to compute a range of K +-nucleus observables, considering how these vary with assumptions about alterations of the K +-nucleon amplitudes within complex nuclei. The observable elastic, inelastic, total and reaction cross sections are approximately...

Description
Summary:We have used an impulse approximation optical model to compute a range of K +-nucleus observables, considering how these vary with assumptions about alterations of the K +-nucleon amplitudes within complex nuclei. The observable elastic, inelastic, total and reaction cross sections are approximately linearly dependent upon the interior K +-nucleon amplitudes, not cross sections. Similar comparisons are made for quasi-elastic scattering, computing the number of nucleons contributing incoherently to the reaction through an eikonal model incorporating enhanced cross sections. All measured observables are consistent with enhanced in-medium K +-nucleon amplitudes.
