The predictions of a multiple curve crossing model (MCC) were compared to experimental observations of various intermultiplet transfers in thermal energy Na/N/sub 2/ collisions. This includes comparisons to the energy dependence and the absolute value of the Na(4D..-->..5S) cross section that was measured in the experimental section of the present work using a crossed beam apparatus. This also includes comparisons with beam data available in the literature. These last experimental results are not always directly comparable to the calculated cross sections. Deconvolution or simulation procedures are then needed. The general agreement between the MCC calculations and the experimental results is good. In many cases it is much better than a factor 2. The cases or disagreement were discussed carefully, and each of them can be attributable to uncertainties in the experiment or in the procedures of deconvolutions and simulations.
