We report on the production of the NaHg molecule via resonant excitation of the sodium D-lines following energy-pooling collisions of laser-excited Na(3 P-2) atoms. In addition to the chemiluminescence on the red NaHg(II1/2-X(1/2)) band system, we observed emission on the blue-band system. Production mechanisms as well as the dependence on particle density and excitation laser intensity are discussed, and the rate coefficients are determined.
