The radiative widths of two 16O levels were determined using photon scattering and self-absorption measurements. The results were Γ0(6.917)=0.0940.004 eV and Γ0(7.117)=0.0540.004 eV. The effective temperature Te of the O atom in a water target is calculated by accounting for the effect of the zero-point molecular vibrations of the atom. The influence of this new value of Te on the Doppler broadening of the nuclear level and hence on the resulting value of Γ0 as deduced from a self-absorption measurement is discussed.
