Comment on “Thermal shape fluctuation model study of the giant dipole resonance in Gd 152 ”

A recent paper [A. K. Rhine Kumar and P. Arumugam, Phys. Rev. C 92, 044314 (2015)] presented calculations of the giant dipole resonance width and $\ensuremath{\gamma}$-ray absorption cross sections for $^{152}\mathrm{Gd}$ at various temperatures and angular momenta and compared these with the experimental data. In the comparison of the cross sections, the authors used the linearized representations of the experimental spectra which actually represent the absorption cross sections divided by the $\ensuremath{\gamma}$-ray energy. In this Comment we make the comparison with the appropriate absorption cross sections derived from the data. The comparison shows a reasonable agreement if the higher value of the dipole-dipole interaction parameter, mentioned in the paper, is used in the calculation.
