【 摘 要 】

The elastic scattering differential cross-sections of 800 MeV/c K+ mesons from 12C and 40Ca have been analyzed using the Ericson's parametrization for the phase shift. It is found that the parameter values obtained by our analysis are significantly different from those obtained from the closed expression for K+ -nucleus amplitude derived by the strong absorption approximation. Next, using the phase shift obtained from the present analysis we calculate the K+ optical model potentials for 12C and 40Ca by the method of inversion. The calculated potentials are compared with the recently determined phenomenological ones.
