Abstract
The temporal behavior of the laser enhanced ionization signal of mercu ry was studied in a quartz cell under low buffer gas pressure. Using f ast electronics and a short (34 ns) laser pulse, it was possible to di stinguish, in one single time-resolved ionization waveform, the non-se lective photoionization component of the signal from that which was du e to collisional ionization from selected levels. Experimental results were shown to agree with those obtained by computer simulation, and o ptimal conditions for deconvolution of the two components were studied . (C) 1997 Elsevier Science B.V.
