Microscopic description of K+ scattering on H, 2H, 4He, 6Li and 12C nuclei using meson exchange theory

Abstract EN

In this research, the total cross sections for the K+ meson interactions with H, 2H, 4He, 6Li, and 12C nuclei for some incident momenta Plab less than 1 GeV/c was calculated.

The K+- nucleon optical potential based on the exchange of three mesons ( ) was derived and also four mesons by adding the ( ) meson between the reactants.

It is shown that both the radial behavior of the real and the imaginary parts of the derived potentials in two cases.

Comparisons between the available experimental data, other theoretical results and our calculated results showed a reasonable agreement.

The extended optical model (by including the meson in the scattering process gave, as expected, results more close to the experimental data.

Further, both theoretical and experimental ratios of the total cross sections of the studied nuclei compared with the total cross section with the deuteron nucleus, showed some medium-nuclear effect in such soft nuclear reactions.
