A dye laser, pumped by a pulsed nitrogen laser has been frequency doubled to excite $Hg2(Og+\to lu)$. The time behavior of the subsequent fluorescence in the uv-band $(3350$ {\AA}) and the visible $(4850$ {\AA}) has been measured to evaluate the kinetics of the system. Time resolved fluorescence spectra have been taken for comparison with such data obtained by high energy (MeV) electron beam excitation. These results indicate a fundamental difference between selective optical and high energy electron beam excitation.
