Abstract

The example of the lowest 1S resonance of the H– anion demonstrates that the resonance energy and its width calculated by way of finding the optimal point using the method of the complex absorbing potential has a systematic error, whose magnitude depends on the parameters of the absorbing potential and on the approximation used to solve the Schrödinger equation. It is shown that the accuracy of the calculation of resonance parameters can be improved if you replace finding the optimal point with averaging over the trajectory closure interval.
