Formation and quenching of XeF and KrF electronic excited states

Research output: Contribution to journalArticlepeer-review


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 (p<225 Torr) Xe (or Kr)/F 2 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.
