摘　　要：用Ｑ３Ｄ磁谱仪及其焦面探测器系统，在９０７２ＭｅＶ处测量了１８Ｏ＋１４８Ｎｄ的弹性散射和非弹性角分布，并利用ＤＷＢＡ和耦合反应道计算程序ＦＲＥＳＣＯ对实验结果进行了拟合结果表明在弹性散射分析中，引入极化势的ＤＷＢＡ计算与耦合道计算有类似的结果另外，还讨论了非弹性散射激发过程中的核库仑激发的相干效应。Angular distributions of the elastic and inelastic scattering of 18 O+ 148 Nd at 90.72 MeV are measured by using the Q3D magnetic spectrometer as well as the focal plane detector system,.The experimental results are reproduced by DWBA and coupled reaction channel calculation code FRESCO. The polarized potential is introduced in the DWBA calculation and the similar results with the coupled channel calculation are obtained.The interference effect of nuclear Coulomb in the inelastic exciting is discussed and the approximate factor described the interference intensity are reduced.
