Abstract：
Elastic differential cross sections for K⁺ mesons scattered from ¹²C and ⁶Li targets at an incident momentum of 715 MeV/c and from(12). ⁴⁰Ca targets at an incident momentum of 800 MeV/c have been studied in this paper. The method of the eikonal phase shift with the first-order correction including the deflection effect due to the coulomb field has been used in the work. By the fitting the theoretical differentical cross sections with the corresponding experimental results we have got the optimum optical potential parameters, which provides some Kind of bases for the microscopic shudy of K⁺ elastic scattering. We gained the total cross sections for the correspondiny scatterings by using the ophcal potential, and compared itwith the experimental data.
