We report the ratio of rate coefficients for the excitation-transfer reaction Na(3P/sub J/) +Na(3P/sub J/')..-->..Na(nL/sub J/'') +Na(3S/sub 1/2/), which has sometimes been labeled energy pooling, measured in a cell at T = 640 K. Rate-coefficient ratios are given for nL/sub J/'' = 4D/sub 3/2/, 4D/sub 5/2/, 4F/sub 5/2/, 4F/sub 7/2/, and 5S/sub 1/2/, each for J = J' = 1/2 and 3/2. We also report the nL/sub J/'' ratios when the 3P states are populated in nearly statistical ratios; these are related to the rate coefficients when J = 1/2 and J' = 3/2.
