    h^{h}S. Tam and M.E. Fajardo, J. Chem. Phys. 99, 854 (1993). I^{I}M. Macler and M. E. Fajardo, Appl. Phys. Lett. 65, 2275 (1994).Author Institution: OLAC PL/RKS, Propulsion Directorate, Phillips LaboratoryWe have previously reported the generation of novel ``tight” metal atom trapping sites in rare gas matrices prepared by laser ablation of metal targetshtargets^{h}. We proposed a microscopic model of the matrix deposition process which attributed this phenomenon to implantation of fast laser ablated atoms into previously deposited matrix layers. We have since attempted to repeat these experiments using a refined laser ablation source capable of rejecting charged species from the laser ablated plumeiplume^{i}. Results on Li, Na, and Al atom doped Ar matrices demonstrate that trapping of laser ablated IONS, not fast metal atoms, are responsible for the observed novel effects

    1^{1} W. Fawzy. M. Mackr, J. P. Nicolai and M. C. Heaven, submitted to J. Chem. Phys. 2^{2} M.A.P. Macler and M. C. Heaven, 14, 43rd Symp. on Molec. Spectrosc. 1988. Work supported by AFOSR under grant 88-0249Author Institution: Department of Chemistry, Emory UniversityVisible laser excitation of matrix isolated iodine produced I.R. emissions that have been resolved into three componenta: the A(3Π1)x(1Σg+)A(^{3}\Pi_{1}) \to x(^{1}\Sigma_{g}^{+}) and A(3Π2)xA(^{3}\Pi_{2})\to x systetas I2I_{2} and the 12P1/22P3/2transition.11^{2}P_{1/2}\to^{2}P_{3/2} transition.^{1} Single photon 193nm excitation of Ar isolated iodine produced a U.V. emission at 380nm(D(3Π2g)A(3Π2u))380 nm (D(^{3}\Pi_{2g})\to A(^{3}\Pi_{2u})) and the I.R. emission systems.2systems.^{2} Further studies of visible excitation of concentrated rere-gas iodine matrices revealed A' fluorescence decay curves which were bi-exponential. The fast component (τ=13±2\tau = 13\pm 2 ms in Ar) corresponded to radiative decay, while a weak, slow component (τ48±4ms)(\tau 48\pm 4 ms) was thought to be a consequence of energy transfer from shallow-bound metastable electronic states. Sequential 2-photon excitation was used to confirm this hypothesis. In one sales of experiments 532nm pulses were used to excite the metastable states. Population in these stases was monitored by using 308nm pulses to excite to the D state. The metastable state decay lifetime was determined by following the DAD'\to A' emission intensity as a function of the delay between the 532 and 308nm pulses. A 51±751\pm 7 ms lifetime was observed, in excellent agreement with the rate at which population was transfered to the A state. Similar results were obtained with a 193nm pump 308nm probe sequence. In this case initial excitation of D' was followed by radiative relaxation into several valence states. The decay of these states was reflected in the delay dependence of the probe laser fluorescence. Spectral and temporal analyses of these experiments will be discussed
