K − - Nucleus Scattering at Low and Intermediate Energies

We calculate K −-nucleus elastic differential, reaction and total cross sections for different nuclei (12 C, 40 Ca and 208 Pb) at several laboratory antikaon momenta, ranging from 127 MeV (momentum of an antikaon produced in the φ-meson decay) to 800 MeV. We use different antikaon-nucleus optical potentials, some of them fitted to kaonic atom data, and study the sensitivity of the results to the considered antikaon-nucleus dynamics. The possibility of using the scattering data to disentangle between different optical potentials, fitted to K −-atom data, is discussed.
