The deexcitation processes of moderately excited sodium atoms have been studied in a pulsed crossed-beam experiment. The time resolution of the sodium beam fluorescence allows the simultaneous observation of intermultiplet and angular momentum transfers. The absolute calibration procedure is described and results are compared with those obtained with different experimental techniques. Partial quenching cross sections of the Na(4P) and Na(4D) states by He, Ar, H/sub 2/, N/sub 2/, O/sub 2/, N/sub 2/O, and SF/sub 6/ are reported.
