Abstract
Electron collisional quenching of the KrF* and XeF* electronically excited state populations in e‐beam‐excited plasmas has been observed. Also, significant enhancement of both XeF* and KrF* fluorescence was obtained in low‐pressure (p2 mixtures with the addition of 12.5–200 Torr helium. Spectral measurements show that this enhancement is not due to helium collisional relaxation of the exciplex vibrational manifold. These effects prohibit a straightforward estimate of the XeF* or KrF* spontaneous radiative lifetimes.Keywords
