Résumé
Les durées de vie des états métastables à 3 électrons (1s 2s 2p) 4P sont déterminées par une technique de coincidence. Les sections efficaces de "quenching" de O2 et de Ne ont été deduites des variations de la durée de vie en fonction de la pression de la cible.
Abstract
Lifetimes of the (1s 2s 2p) 4P state in oxygen and in neon have been measured with a pulsed beam delayed Auger electron coincidence apparatus. Quenching cross sections have been extracted from the target pressure-dependent lifetimes t(p). Lifetimes t(0, p→0) = (25.9 ± 2) nsec and t(Ne, p→0) = (12.0 ± 1) nsec have been determined.
