Elastic differential cross sections for K+ mesons scattered from C-12 and L
i-6 targets at an incident momentum of 715 MeV/c and from C-12,Ca-40 target
s 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 includin
g the deflection effect due to the coulomb field has been used in the work.
By the fitting the theoretical differentical cross sections with the corre
sponding experimental results we have got the optimum optical potential par
ameters, which provides some kind of bases for the microscopic shudy of Kelastic scattering. We gained the total cross sections for the correspondin
y scatterings by using the optical potential, and compared itwith the exper
imental data.
