【正】 The differential cross sections of the inelastic scattering of antiproton leading to the2<sup>+</sup> excited stae of <sup>18</sup>O are calculated at 178.4 MeV by the Eikonal approximation and thecollective model of nucleus.It may be concluded that the 2<sup>+</sup> state is a quadruple rotationalstate.The results are in good agreement with experimental data.
