Large-Angle Elastic Scattering of π⁺ and π^- from ¹⁶O at 114 MeV

Abstract：

The large-angle elastic cross sections for the scatterings of the π⁺ and π^- from ¹⁶O at 114 MeVare calculated using the first-order optical potential constructed from the α-particle model of ¹⁶O. The calculated results show that obvious improvement is obtained on the calculations employing the first-order optical potential of the Kisslinger type.
