在外部复标度法中，汉密尔顿算子的坐标被从半径R = 0开始的常数因子标度。我们表明，这一过程中诱导的动能项，必须解释为δ函数的衍生物的奇异性。
In the method of exterior complex scaling the coordinates of the Hamilton operator are scaled by a constant factor starting at a radius R≠0. We show that this procedure induces a singularity in the kinetic-energy term which must be interpreted as the derivative of a δ function.
