Measurement has been made of the {sup 18}O({gamma},{ital pn}+{ital np}) cross section. The cross section rises to a maximum of 1.2 mb at 27.5 MeV, approximately one-tenth of the total ({gamma},{ital n}) cross section there. The integrated cross section is correspondingly small (11.8 Mev mb to 43 MeV). As a result, the assignments of isospin distribution in the giant dipole resonance made by Woodworth {ital et} {ital al}. (Phys. Rev. C 19, 1667 (1979)) are unaffected by neglect of this reaction channel.
