We report photoassociation spectroscopy of {sup 174}Yb for the {sup 1}S{sub 0}-{sup 1}P{sub 1} transition at 1 {mu}K, where only the s-wave scattering state contributes to the spectra. The wave function of the s-wave scattering state is obtained from the photoassociation efficiency, and we determine that the C{sub 6} potential coefficient is 2300{+-}250 a.u. and the s-wave scattering length is 5.53{+-}0.11 nm. Based on these parameters, we discuss the scattering properties of s- and d-wave states.
