Abstract:

The differential cross sections for the K^--nucleus elastic scattering at about P_K = 800 MeV/c are calculated in the phenomenological isobar-doorway model. The many-body corrections on Y^* resonances in nuclei are represented by the resonance energy shift ΔE and width-modification factor β. The parametrizations given by Gopal et al. are used for the resonance amplitudes. The effects of ΔE and β on the cross sections are investigated in detail. The results are compared with the available experimental data for the K^- elastic scattering on ¹²C and ⁴⁰Ca at P_K = 800 MeV/c. The calculated cross sections are in good agreement with the data. However, the cross sections are not very sensitive to ΔE and β.
