用冻结核处理来表示剩余离子的剩余电子，计算了氖和氩在不同光子能量和电子能量分担下的单光子双电离三重微分截面.角分布符合所有现有的实验数据，表明尽管它的简单的方法可以可靠地处理复杂的目标的双电离。氦、氖和氩在相同的相对过剩能量下进入相同的末态对称的截面的比较揭示了每个靶中电子相关作用的独特特征。
Triply differential cross sections are calculated for one-photon double ionization of neon and argon at various photon energies and electron energy sharings by using a frozen-core treatment to represent the remaining electrons of the residual ion. Angular distributions agree well with all existing experimental data, showing that in spite of its simplicity the method can treat the double ionization of complex targets reliably. A comparison of the cross sections for helium, neon, and argon into the same final state symmetry at the same relative excess energies reveals a distinctive signature of the role of electron correlation in each target.
