摘    要:利用Berakdar和Briggs对BBK波函数Sommerfeld参数的修正结果(即考虑第三个粒子存在对两个粒子间相互作用的影响),并考虑了入射道的库仑相互作用及出射电子的交换对称性,计算了在共面-等能分享-固定相对角度几何情况下,入射能量分别为:58.4、68、81.6、108.8和174.4eV的He+(e,2e)反应三重微分截面.结果表明,在较低碰撞能量散射中,入射道库仑场对两体碰撞起主要作用. A corrrelated three body continuum wavefunction proposed by Brauner et al has been recently modified further to allow for three body effects by introducing Somerfeld parameters (Berakdar and Briggs). The triple differential cross sections for electron impact ionization of He+ in coplanar equal energy sharing and fixed relative angle geometry are calculated. The initial channel wavefunction involves a Coulomb wavefunction due to the long range Coulomb attraction between the incident...

Abstract:A corrrelated three body continuum wavefunction proposed by Brauner et al has been recently modified further to allow for three body effects by introducing Somerfeld parameters (Berakdar and Briggs). The triple differential cross sections for electron impact ionization of He+ in coplanar equal energy sharing and fixed relative angle geometry are calculated. The initial channel wavefunction involves a Coulomb wavefunction due to the long range Coulomb attraction between the incident...
