摘要：
We present a new complex scaling method for the study of resonance eigenstates without the use of basis set expansions. The procedure does not require the computation of potential matrix elements; the eigenvectors provide directly the values of the resonance wave functions at the space grid points. The simplicity, efficiency, and reliability of the method is illustrated by a case study of the tunneling in an anharmonic oscillator. © 1990.
