δ' potential arising in exterior complex scaling

Abstract
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.
