Query: 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.
