    "abstract": "We study the time-resolved photoassociation of ultracold sodium in an optical\ndipole trap. The photoassociation laser excites pairs of atoms to molecular\nstates of large total angular momentum at high intensities (above 20\nkW/cm$^{2}$). Such transitions are generally suppressed at ultracold\ntemperatures by the centrifugal barriers for high partial waves. Time-resolved\nionization measurements reveal that the atoms are accelerated by the dipole\npotential of the photoassociation beam. We change the collision energy by\nvarying the potential depth, and observe a strong variation of the\nphotoassociation rate. These results demonstrate the important role of light\nforces in cw photoassociation at high intensities.",
