TEMPERATURE-EMISSION PROFILE RELATION IN EXCIPLEX KR-ASTERISK AR EMISSIONS

The fast O+(P-3(1)) and slow 1(P-3(2)) relaxed exciplex KrAr emission s near 9.26 eV (134 nm) have been observed in a large density and temp erature range. The band half widths are found to be only temperature d ependent, a result similar to that previously reported for the rare ga s excimers (homonuclear), and revealing a very week environmental infl uence. From a simple model we derive omega(e) = 60 cm(-1) for the vibr ational constant and Delta(O) = 2400 cm(-1) for the width extrapolated at O Kelvin.
