    "abstract": "For two discrete-level quantum systems in interaction, we follow the\ndisplacement in the complex plane of the eigen-energies of the compound system\nwhen the spectrum of one of the two systems becomes continuous. These new\npoints are usually called resonances. This allows us to define and to calculate\na critical value of the coupling constant which separates two well-known\ncoupling regimes. We also give an example of these resonances for the hydrogen\natom coupled to the continuum of the states of the transverse electromagnetic\nfield in the vacuum. We justify that some resonances be neglected.",
