| 英文摘要 | The momentum dependent K--nucleus optical potentials are obtained based on the relativistic mean-field theory. By considering the quarks coordinates of K- meson, we introduced a momentum-dependent "form factor" to modify the coupling vertexes. The parameters in the form factors are determined by fitting the experimental K--nucleus scattering data. It is found that the real part of the optical potentials decrease with increasing K- momenta, however the imaginary potentials increase at first with increasing momenta up to P-k=450 similar to 550 MeV and then decrease. By comparing the calculated K- mean free paths with those from K(-)n/K(-)p scattering data, we suggested that the real potential depth is V-0 similar to 80 MeV, and the imaginary potential parameter is W-0 similar to 65 MeV. |
