By using a rather general electron-phonon interaction Hamiltonian and taking into account the confinement of phonons, we calculated the energy shift, level broadening, and effective mass. It was found that the electron-phonon interaction makes a very significant contribution to all of them near resonance. © 1990 The American Physical Society.[SDGs]SDG7journal article10.1103/PhysRevB.42.110862-s2.0-35949008296WOS:A1990EM72700031
