Abstract

The differential cross sections of the elastic scattering of K $^{±}$ on $^{40—48}$ Ca are calculated in the framework of eikonal approximation. The theoretical values obtained by using different parameters are compared. Through adjusting the parameters of the neutron distribution, the improvement of the coincidence between the theoretical values and the experimental data is arrived. The result shows that the r. m. s radius of the neutron distribution of $^{40}$ Ca is smaller than that of the proton. (about 0.15fm smaller) and the surface thickness of the neutron distribution of $^{40}$ Ca is thinner than that of proton. This is consistent with the results of computation made by H. F. method and agrees with the analysis of elastic scaatering of protons in the mediate energy on $^{40}$ Ca by other authors.
