Phys. Rev. C 68, 039801 (2003) [2 pages]Comment on “Angular momentum gated giant dipole resonance measurements in the reaction 28Si+58Ni at E(28Si)=100 and 125 MeV”Received 17 March 2003; published 18 September 2003 In a recent paper, the giant dipole resonance width was studied as a function of angular momentum in the nucleus 86Mo. The width of the resonance was found to be constant over a spin range of (0–40)ħ. It was concluded that the angular momentum dependence for 86Mo differs from that of Sn isotopes. We compared both datasets with a phenomenological formula based on the thermal fluctuation theory. The 86Mo data are inconsistent with the formula in contrast to the previously analyzed Sn data, which seems to indicate that the angular momentum dependence of the phenomenological model is not universally applicable. © 2003 The American Physical Society URL:
