Comment on ''Resonant excitation of the reaction 180Tam(γ,γ')180Ta''

We point out that the large integral cross section values reported for the 180Tam(γ,γ')180Ta reaction by Collins et al. correspond to transition strengths exceeding the recommended upper limits. The small overall cross section ratio of the aforementioned and the 115In(γ,γ')115Inm reactions is shown to be an indirect piece of evidence against the enormous integral cross sections. Collins et al. used the 87Sr(γ,γ')87Srm reaction to verify their calculated photon flux, but did not identify the observed activation levels. We identify four photoactivation levels of 87Sr at 1228.42 keV, 5/2+, 1770.46 keV, 5/2+, 1919.9 keV, 7/2+, 2706.5 keV, 9/2+, and deduce the existence of (at least) a further one around 2.6 MeV. These new data suggest that the calculated photon flux used by Collins et al. should be rechecked
