Energy pooling collisions in pure cadmium vapors

We have investigated energy pooling processes in pure Cadmium vapors excited by a pulsed laser beam resonant with the Cd(51S0)→Cd(53P1) intercombination transition. Starting from the measured fluorescence intensities, we have determined the cross sections for the processes populating the 53Dj levels using a rate equation system and accounting for the radiation trapping phenomenon.
