Eikonal Approximation for K+–Nucleus Elastic Scattering
Abstract
The elastic scattering of kaons from different targets 6Li, 12C, and 40Ca at energies 635, 715, and 800 MeV have been studied. The equivalent local potential form of Kisslinger optical potential with the eikonal approximation using Wallace expansion up to the 2nd order have been used. The potential depends on the density of the target nuclei, and the scattering amplitude parameters. Satisfactory fits to the elastic scattering experimental data are obtained.
