An unsymmetrized nucleon wave function obtained by adding the possible quarkdiquark structure to the usual spatially symmetric wave function is used to calculate the elastic proton-antiproton multiple scattering amplitudes. Numerical computation is made on the double scattering term. Results show that the amplitude from the unsymmetrized wave function is larger in absolute magnitude than that from the symmetric one. The difference becomes more visible as the momentum transfer increases. This feature is briefly discussed.
