Recent laser results in XeF* show a considerable improvement when the Ar buffer is replaced by Ne. In this letter we report on the investigations of the formation and quenching processes in typical laser mixtures of Ne/Xe/F/sub 2/. From our experimental observations, it appears that the Ne ions formed by the fast electrons do not form Xe/sup +/ by a direct charge transfer. We have also determined that the two-body quenching of XeF* by Ne is negligible, while the three-body quenching rate constant is 2.5 x 10/sup -33/ cm/sup 6//sec. Finally, the three-body quenching rate constant for XeF*+Xe+Ne is 7.8 x 10/sup -31/ cm/sup 6//sec.
