By tuning a single-mode dye laser across the Doppler profile of a molecular resonance we can very the average relative velocity from $450^{\circ} K$ (line center) to $2400^{\circ} K$ (=2 Ghz. detuned). We made $measurements^{2}$ for four different values of $\Delta$ for each of three $J_{i}$’s. Cross sections for $j_{i}=66$ increase with velocity whereas those for $j_{i}=38$ and 16 stay constant or decrease. A dramatic decrease is observed for $j_{i}=164$ and large $\Delta$. en_US dc.format.extent 101409 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title VELOCITY DEPENDENCE OF ROTATIONAL ENERGY TRANSFER RATES IN $Na_{2}{^{*}}$-Xe en_US dc.type article en_US
