Microscopic Description of K+ Scattering on 4He, 16O and 40Ca Nuclei using Meson Exchange Theory
Abstract
We have calculated the total cross section for k+-4He, 16O, 40Ca, intes at incident momenta of the kaon Plab<1GeV . We derived the K+-nucleon optical potential according to the exchange of 3- mesons (segma,roh,omega) and also for 4- (segma,roh,omega, segma0) exchanged between the reactants. We showed both of the radial behavior of the real and the imaginary parts of the derived potential. Comparisons between the available experimental data, other theoretical work and the calculated total cross sections for the three studied nuclei which have shown a reasonable agreement. The extended four mesons exchanged optical potential gave better close results to the experimental data. Further, ratios of the total cross sections of the studied nuclei with respect to the total cross section with the deuteron nucleus for the two applied optical potentials were given. In addition, the ratio of the theoretical result of the total cross section for the interaction of the K+ meson with the deuteron was compared with the corresponding experimental one to evaluate our theoretical results in a more clear manner.
