In terms of stationary states we have bound states and free(plane wave or Coulomb) states
Autoionizing states are free(E>0), e.g. continuum, but localized states(resonances). Hence
wavepackets consisting of a band of plane or Coulomb waves. I understand they may be long-lived, longer than the experiment and that ionization may occur by a bound state acquiring some energy, staying localized for a while in an autoionizing state. But why do we need to include them and not use the simpler bound+free(plane or Coulomb ) basis? After all autoionizing states should be nothing more than a linear combination of plane or Coulomb waves
