Abstract：
Under reverse kinematics, elastic scattering of ¹⁷F and ¹⁸Ne on proton is studied. The experimental differential cross sections were measured. A kind of global optical potential with the CH89 parameters is used to describe the radioactive nucleus as an initial optical potential parameters. The experimental differential cross section data are analyzed by using the theoretical calculation code DWUCK4 with the distorted wave Born approximation and parameter search subroutine ABOD which automatically searches the suitable parameters. Then the optical potential parameters of scattering ¹⁷F and ¹⁸Ne on proton are obtained. From the analyses of the optimized parameters, the real central potential mean square radii of ¹⁷F and ¹⁸Ne, 3.239fm and 3.317fm are deduced, respectively.
