Measured Lifetimes of Some <i>A</i> 2Π<i>u</i> Vibrational Levels of N2+ Molecules

Abstract

A delayed coincidence technique has been used to measure the radiative lifetimes of the v′=2, 3, and 4 levels of the A 2Πu State of N2+. The data closely follows the simple theory for collisional deactivation. The lifetimes, extrapolated to zero pressure, are 9.4± 1, 9.5± 1, and 8.9± 1 μ sec for the v′=2, 3, and 4 levels, respectively.
