  1. The coupled equation method ( cem ) has been improved to calculate 4s subshell of mnl by adding 3d ~ ( 5 ) ( ( 4 ) ~ x ) 4s ( ( 5 ) ~ x ) channels, which were verified to play a key role to the magnitude of resonance structure due to the interaction between 4s kp transition and 3p 3d excitation. our calculation shows higher symmetry and a solo peak near 51. 7ev, which is in better agreement with experimental data than garvin ' s calculation. except 3p 3d giant resonance, there are obvious 3p nd ( n > 4 ) rydberg resonances with width in the total cross section of mnl

    在研究錳原子4s殼層的共振結構時，我們首次在耦合方程方法中加入了3d ~ 5 （ ~ 4x ） 4s （ ~ 5x ）通道與大共振之間的相互作用，發現這類通道對於4s殼層的共振結構具有較大的貢獻，從而改善了在耦合方程方法中只考慮基態3d ~ 5 （ ~ 6s ） 4s （ ~ （ 7 ， 5 ） s ）的缺陷，為精確計算其他過渡金屬原子外殼層的共振結構做了很好的鋪墊。
  2. Fourthly, the resonance structure disappears in the energy dependence of integral cross - section due to the summation of partial waves

    另外在積分散射截面中，由於對各個分波求和，能量幾率曲線的振動結構消失了。
  3. This dissertation concentrates on photoionizaiton of mnl and mnll including resonance structure in the framework of many - body perturbation theory ( mbpt ). more accurate results were obtained by using the new approach to calculate resonance structure and photoionization cross section

    首先針對錳原子或離子不同殼層的光電離結構進行特定的理論分析，然後通過合理的選擇勢能及共振結構的計算方法，並考慮高階關聯，得到了一系列新的更為精確的光電離截面及共振結構。
