A semiclassical model is developed to describe the two-electron dynamics of the process of autodetachment. A formula derived for the partial width of a doubly excited state represents a product of an amplitude and phase factors. An anomalous width behavior is predicted for states near a threshold when the orbital angular momentum of the outer electron is high. Oscillations of the phase factor, as a function of energy, determine the functional behavior of relative widths in the region farther from threshold for a given series of states.
开发了一种半经典模型来描述自电离过程的双电子动力学。为双激发态的部分宽度推导的公式表示振幅和相位因子的乘积。当外层电子的轨道角动量较高时，预测接近阈值的状态会出现异常宽度行为。相位因子作为能量的函数的振荡决定了给定系列状态在远离阈值区域中相对宽度的函数行为。
