The observation of a heteronuclear reverse energy pooling process is reported. The cross sections for the collision processes Cs(8D,9D)+Na(3S)→Cs(6P)+Na(3P) have been measured. In the experiment the caesium atoms were excited in two steps to the 9D 3/2(8D 3/2) state. A double-modulation technique has been used to select the fluorescence contributions at the Na(3P J) exit channels due only to the above reactions. The ground state sodium atom density was measured by the absorption of line from a Na hollow-cathode lamp. The measured density and fluorescence intensities have been used to obtain reverse energy-pooling rate coefficients. The contribution to the rate coefficients from other processes is discussed.
