| Abstract: | The influence of the inclusion of spin orbit interaction on the antiproton optical potential is considered in this paper.The elastic scatter- ing differential cross section (dσ)/(dΩ),analyzing power A_y(θ) and spin rota- tion function Q(θ) were calculated respectively for target nuclei ~(12)C,~(16)O, ~(40)Ca and ~(208)Pb at incident energies E=48Mev and 180 Mav.Experimental data showned that the optical potential after including the spin orbit nteraction can also fit in with the differential cross section very well. The angular distributions of analyzing power A_y(θ) and spin rotation func- tion Q(θ) were given for various nuclei at different energies. |
