On the three-body continuum spectrum of He-6
  In recent publications Cobis, Fedorov, and Jensen claim the existence of several previously unknown low-lying narrow resonances in He-6. I show that the distribution of the S-matrix poles corresponding to these states is unphysical. This casts doubt on the results of those works concerning resonances.
