Tóm tắt

This paper presents the computational scheme and calculation results of metastable states in scattering and eigenvalue problems for complex potential barriers. For the scattering problem, the wave functions with S-scattering matrix are calculated at fixed real-valued energy of an incident wave, and the eigenvalue problem with corresponding eigenvalues are calculated as well. Then, we consider the wave functions of metastable states in the vicinity of these resonance energies for two of these problems. The solution to the problems is performed using the authors' software package with the high-accuracy finite element method. The calculation results are shown in table and graph form.
