Comment on "Evidence for narrow resonant structures at W approximate to 1.68 GeV and W approximate to 1.72 GeV in real Compton scattering off the proton"

We comment on the statement by Kuznetsov et al. that the structure around W=1.72 GeV seen in the beam asymmetry in Compton scattering off the proton is not observed in the total cross section of η photoproduction on the neutron.
