    • We neglect here the fact that there also exist 'long-lived' continuum states in the open system under consideration, the decay rates of which can be comparable to or smaller than that of the energetically lowest quasi-bound state. In practice, the unwanted convergence into such continuum states can be avoided by starring with an initial wavefunction that is rather close to the quasi-bound state to be calculated
