摘要 用自旋平均静态交换势下的三体扭曲波波恩近似计算了d轨道电子 (Ag+ (4d10 ) )在共面非对称几何条件下的三重微分截面 ,结果表明在高入射能的条件下 ,随散射电子角度θa的增加 ,bina ry峰和recoil峰分裂的个数都会增加 ,电子的电离振幅会随之下降 ,d电子的三重微分截面比s。 The three-body distorted-wave Born approximations with sp in-averaged static exchange potential have been used to calculate the electron-impact triple-differential ionization cross sections(TDCS) of 4d orbital (Ag + (4d 10 )) in coplanar asymmetric geometry. At high incident energy(E o =1 000 eV), ionization amplitude of Ag + decreases with increase of scattered angle(θ a )and the shape of the binary peak and recoil peak is more complicated than s- and p-electron: binary and recoil peaks of d-electron split into many small peaks. It may be caused by the difference in shape of wavefunction. The shape of the d-electron wavefunction is more complicated than that of the s and p electron wavefunctions.
