Elastic and inelastic scattering of K⁺ from nuclei

Local optical model calculations have been carried out for elastic, inelastic, total, and reaction cross sections of K⁺ from ²H, ⁶Li, ¹²C, and ⁴⁰Ca at kaon laboratory momenta ranging from 488 to 800MeV/c. Zero-range distorted-wave Born approximation calculations have been carried out for elastic and inelastic scattering of K⁺ leading to the lowest 3⁺ state in ⁶Li and 2⁺ and 3^- states in ¹²C. Local optical potential is also used to estimate quadrupole noncentral contributions to elastic K⁺ scattering from the 1⁺ ground state of ⁶Li, and these are found to be very small. Deformation lengths extracted from inelastic scattering are similar to those deduced from other works. Our calculations adequately reproduced the kaon scattering data.
