We have investigated photoassociation (PA) spectra of ultracold 88Sr atoms near the 5s2  1S0+5s5p  1P1 atomic asymptote. The intensity modulation of the PA lines was used to reconstruct the ground-state scattering wave function, whose last nodal point was determined to be r0=3.78(18)  nm. The PA lines also determined a precise lifetime of the 1P1 state to be 5.263(4)  ns.
