摘要: Excitation of atomic krypton in the presence molecular fluorine by a wavelength‐selective 2.5‐ns‐long argon excimer photolytic source was used to initiate reaction sequence resulting formation excited KrF. The radiative lifetime KrF* laser transition found be 9 ns at high‐pressure limit. This is good agreement with calculated values. rate constant for two‐body quenching F2 5.7±0.5×10−10 cm3 s−1 and three‐body Kr 2.9±0.3×10−31 cm3 s−1.
