| 摘 要： | 在Ｂｅｒａｋｄａｒ工作的基础上，从三体库仑连续问题中动量相关的角度导出了对称和非对称两种几何件下的有效索末菲参量，计算了入射能为５０ｅＶ时电子入射离化Ｈｅ原子的三重微分截面，并将计算结果绝对测量结果以及未修正的ＢＢＫ理论结果、ＣＣＣ（ｃｏｎｖｅｒｇｅｎｔ ｃｌｏｓｅ－ｃｏｒｐｌｉｎｇ）理论结果进行了比较，同时与我们早期模型的结果进行了比较。

| Abstract: | Following the work of Berakdar (Phys.Rev.A53,2316,(1996)) ,the momentum correlation in the three-body Coulomb continuum problem is considered by the introduction of effective Sommerfeld parameters for both symmetric and asymmetric geometry. The triple differential cross sections for electron impact ionization of atomic helium at incident energies of 50eV in asymmetric geometry are calculated. Results of this approach are compared with the absolute measurements, the results of the BBK model without modification, the convergent close-coupling calculations and the results of our earlier model. |
